X86 specific BaseLib API AsmLfence() was introduced to address the Spectre
Variant 1 (CVE-2017-5753) issue. The purpose of this API is to insert
barriers to stop speculative execution. However, the API is highly
architecture (X86) specific, and thus should be avoided using across
generic code.
To address this issue, this patch will add a new BaseLib API called
SpeculationBarrier(). Different architectures will have different
implementations for this API.
For IA32 and x64, the implementation of SpeculationBarrier() will
directly call AsmLfence().
For ARM and AARCH64, this patch will add a temporary empty implementation
as a placeholder. We hope experts in ARM can help to contribute the actual
implementation.
For EBC, similar to the ARM and AARCH64 cases, a temporary empty
implementation is added.

On some architectures, the maximum representable address deviates from
the virtual address range that is accessible by the firmware at boot
time. For instance, on AArch64, UEFI mandates a 4 KB page size, which
limits the address space to 48 bits, while more than that may be
populated on a particular platform, for use by the OS.
So introduce a new macro MAX_ALLOC_ADDRESS, which represent the maximum
address the firmware should take into account when allocating memory
ranges that need to be accessible by the CPU at boot time.

ARM uses the low order bit of a branch target address to decide in
which execution mode (ARM or Thumb) a function needs to be called.
In order for this to work across object files, ELF function symbols
will have the low bit set if they were emitted in Thumb mode and
cleared otherwise. This annotation is only emitted if the ELF symbols
are annotated as function, since taking the address of some data
symbol (e.g., a literal) should not produce a value with the low bit
set, even if it appears in an object file containing Thumb code.
This means that all functions coded in assembler must have this
function annotation, or they may end up getting called in the
wrong mode, crashing the program.

This reverts commit 82379bf660.
On AArch64, we can only use 48 address bits while running in UEFI,
while the GCD and UEFI memory maps may describe up to 52 bits of
physical address space. For this reason, MAX_ADDRESS was reduced
to 48 bits, to ensure that the firmware does not inadvertently
attempt to allocate memory that we cannot access.
However, MAX_ADDRESS is used in runtime drivers as well, and
runtime drivers may deal with kernel virtual addresses, which have
bits [63:48] set. In fact, the OS may be running with 64 KB pages
and pass addresses into the runtime services that use up to 52
bits of address space, either with the top bits set or cleared,
even if the physical address space does not extend beyond 48 bits.
In summary, changing MAX_ADDRESS is a mistake, and needs to be
reverted.
