This patch reduces the size of IA32 binaries by ensuring that
no .debug_frame / .eh_frame sections are generated through forcing
SEH exception model, which is already the default in clang for X64.
EDK II does not support exceptions, and in future we should disable
them instead of switching to some other variant. Currently this
is not possible due to the following LLVM bugs:
https://bugs.llvm.org/show_bug.cgi?id=45324https://bugs.llvm.org/show_bug.cgi?id=45325
Upon applying this patch OvmfPkgIA32.dsc compilation in DEBUG mode
gets the following size decrease with clang 9.0.1.

The call stack unwindability of the COFF X64 binary requires
the binary to remain the pdata and xdata sections.
Details see the MSVC X64 calling convertion doc in below link:
https://docs.microsoft.com/en-us/cpp/build/x64-calling-convention
Current build options discard or zero the data in pdata and xdata
sections which cause the debugger cannot correctly unwind the
X64 binary call stack in the runtime.
Enhance the build options to force emit the unwind tables and
keep the data of pdata and xdata sections correct in the binary.

Compiler cache can greatly improve the build performance and
guarantee the build result safe. In our testing, the compiler
cache can improve the overall clean build time usually by 30+%
in linux and 10+% in windows. The compiler cache are very fit
to improve the Continuous Integration (CI) build performance.
For linux compiler cache (ccache) enabling, there is no need
to update edk2 code.
Below link has the ccache enabling referencd steps:
https://github.com/shijunjing/edk2/wiki/
Edk2-compiler-cache-enabling-steps-on-Linux
For windows compiler cache (clcache) enabling, we need update
the .PDB debugging file producing option from /Zi to /Z7,
which is to let the C object file contain its full symbolic
debugging information rather than produces a separated PDB file
for all obj files per folder. "PDB files are generated by a different
process (mspdbsrv). They arrive or are updated on disk after
cl completes a compilation or linking operation. One huge problem
with caching them is that the pdb files are input files as well as
outputs. mspdbsrv updates the file with new debug information if
the file exists beforehand. If there are several compilations going
on at once targetting the same pdb then the order the pdb gets
updated is unpredictable. All this makes caching very hard."
The /Zi issue more detail disccusion can be found:
https://github.com/frerich/clcache/issues/30
Please be aware that this change has no any impact to edk2 module
level PDB file generation, and we still can get the PDB debug file
for a .efi module. The /Z7 only impact intermediate obj files level
PDB file, which is current one PDB file (vc140.pdb) per obj folder.
Below link has the clcache enabling referencd steps:
https://github.com/shijunjing/edk2/wiki/

*Edk2 source code debugger
*Various hardware and software debuggers
*Uefi code coverage tools

"tools_def.template" currently suggests, in the documentation of the
LzmaF86Compress utility, that said tool is generally unhelpful on binaries
built with the GCC44 toolchain, relative to LzmaCompress.
This statement doesn't apply to the GCC48 toolchain. I compressed 126
NOOPT_GCC48/IA32 unique EFI modules (built with gcc-4.8.5, as part of
OVMF) with both LzmaCompress and LzmaF86Compress. I repeated the same for
117 NOOPT_GCC48/X64 unique EFI modules. On average, the LzmaF86Compress
output size was 92.4% of the LzmaCompress output size in the IA32 case
(best relative compression: 86.01%, poorest relative compression: 97.47%
-- still a win). In the X64 case, the LzmaF86Compress output size was
92.95% of the LzmaCompress output size, on avarege (best relative
compression: 87.69%, poorest relative compression: 97.65% -- again, still
a win).
Given the consistent improvement from LzmaCompress to LzmaF86Compress,
remove the statement (rather than updating it to GCC48).

No GCC47 definitions exist at this point, so remove the GCC47
documentation too, from "tools_def.template".

The last patch decremented references on a number of DEFs. They can be
classified into three groups:
(a) those that remain used by multiple toolchains (refcount >= 2):
- GCC_ASLCC_FLAGS
- GCC_ASLPP_FLAGS
- GCC_HOST_PREFIX
- GCC_IA32_RC_FLAGS
- GCC_PP_FLAGS
- GCC_VFRPP_FLAGS
- GCC_X64_RC_FLAGS
- IASL_FLAGS
- IASL_OUTFLAGS
- UNIX_IASL_BIN
(b) those that are only used by GCC48 (refcount == 1):
- GCC47_ASM_FLAGS
- GCC47_IA32_CC_FLAGS
- GCC47_IA32_DLINK2_FLAGS
- GCC47_IA32_X64_ASLDLINK_FLAGS
- GCC47_IA32_X64_DLINK_FLAGS
- GCC47_X64_CC_FLAGS
- GCC47_X64_DLINK2_FLAGS
- GCC47_X64_DLINK_FLAGS
(c) those that are no longer used (refcount == 0):
- GCC47_IA32_PREFIX
- GCC47_X64_PREFIX
For the members of class (b), expand their definitions at the referring
sites, and remove their definitions.
For the members of class (c), remove their definitions.

Remove the "leaf" definitions for GCC47. These definitions are never
referenced in "tools_def.template" (they are the last GCC47 mentions in
the file), so their removal can't break other definitions. Instead, their
erasure turns other definitions into leaves (subject to further removal).

DLINK_COMMON definitions are not consumed by "build_rule.template";
instead, DLINK_COMMON definitions (internal to "tools_def.template") were
invented for sharing options between ASLDLINK_FLAGS and DLINK_FLAGS.
However, this intent doesn't actually apply to
GCC48_IA32_X64_DLINK_COMMON: it is never consumed. Furthermore, the
GCC45..GCC47 instances of IA32_X64_DLINK_COMMON too lead up to
GCC48_IA32_X64_DLINK_COMMON only -- they form a dead-end. Remove them
altogether, in order to simplify the subsequent patches.

This drops ARM and AARCH64 support from the GCC46 and GCC47 toolchain
definitions, which are on the list to be removed, along with VS2003,
VS2005, VS2008, VS2010, DDK3790, UNIXGCC, GCC44, GCC45, ELFGCC, CYGGCC,
ICC, ICC11 and MYTOOLS.
Since GCC46 and GCC47 are the only ones on that list that support ARM
and/or AARCH64, let's give Liming a hand and cover the ARM side of
things first, so that everything that remains to be removed is x86
only.

The 'arm-linux-gnueabihf' target triplet we use for CLANG35 and
CLANG38 specifies a hardfloat target, and so the binaries that are
emitted are annotated as using VFP registers for passing floating
point arguments, even though no VFP is used anywhere in the code.
This works fine as long as we don't try to link against code
that uses software floating point, but combining object files
with different floating point calling conventions is not permitted.
So switch to the softfloat arm-linux-gnueabi triplet instead.
This affects both the name Clang uses when invoking the linker,
and the arguments it passes to it, and we are mostly interested
in the latter (since any version of GNU ld.bfd will do the right
thing as long as it targets EABI ARM)
For native builds, this change has no effect, since the unprefixed
system linker will take priority, and so Clang will pass the right
arguments to whichever linker happens to be the system linker.
For cross builds, the fact that Clang composes the name of the
linker by prefixing '-ld' with the target triplet implies that
users will have to switch to a version of binutils that targets
arm-linux-gnueabi rather than arm-linux-gnueabihf. Note that the
GCCx toolchain targets can use either when building for ARM so this
does not create a need to install two versions of the ARM cross
toolchain. Also, note that all ARM toolchains in the GCC family
are already documented as requiring a toolchain that targets
arm-linux-gnueabi and not arm-linux-gnueabihf.

The ARM linker may emit veneers, i.e., trampolines, when ordinary
direct relative branches cannot be used, e.g., for Thumb interworking
or branch targets that are out of range.
Usually, such veneers carry an absolute reference to the branch
target, which is problematic for us, since these absolute references
are not covered by annotations that are visible to GenFw in the
PE/COFF conversion, and so these absolute references are not fixed
up by the PE/COFF loader at runtime.
So switch to all ARM GNU ld toolchains to position independent veneers.
