Michael Kubacki edd46cd407 UefiCpuPkg/SmmCpuFeaturesLib: Add Standalone MM support
REF:https://bugzilla.tianocore.org/show_bug.cgi?id=3218

Adds an INF for StandaloneMmCpuFeaturesLib, which supports building
the SmmCpuFeaturesLib code for Standalone MM. Minimal code changes
are made to allow reuse of existing code for Standalone MM.

The original INF file names are left intact (continue to use SMM
terminology) to retain backward compatibility with platforms that
use those INFs. Similarly, the pre-existing C file names are
unchanged to be consistent with the INF file names.

Note that all references in library source files to PiSmm.h have
been changed to PiMm.h for consistency.

Michael Kubacki 2002e950ea UefiCpuPkg/SmmCpuFeaturesLib: Cleanup library constructors
There's currently two library instances:
  1. SmmCpuFeaturesLib
  2. SmmCpuFeaturesLibStm

There's two constructor functions:
  1. SmmCpuFeaturesLibConstructor()
  2. SmmCpuFeaturesLibStmConstructor()

SmmCpuFeaturesLibConstructor() is called by
SmmCpuFeaturesLibStmConstructor() since the functionality in that
function is required by both library instances.

The declaration for SmmCpuFeaturesLibConstructor() is embedded in
"SmmStm.c" instead of being declared in a header file. Further,
that constructor function is called by the STM specific constructor.

This change moves the common code to a function called
CpuFeaturesLibInitialization() which is declared in an internal
library header file "CpuFeaturesLib.h". Each constructor simply
calls this function to perform the common functionality.

Additionally, SmmCpuFeaturesLibConstructor() is moved from
SmmCpuFeaturesLibNoStm.c into a instance-specific file allowing
SmmCpuFeaturesLibNoStm.c to contain no STM implementation agnostic
to a particular library instance.

Michael Kubacki 3e062ea498 UefiCpuPkg/SmmCpuFeaturesLib: Move multi-instance function decl to header
FinishSmmCpuFeaturesInitializeProcessor() is a multi-instance
internal library function that is currently not declared in a
header file but embedded in "SmmCpuFeaturesLib.c".

This change cleans up the declaration moving it to a new header
file "CpuFeaturesLib.h" and removing the local declaration in
"SmmCpuFeaturesLib.c".

Liming Gao 1c7a65eba7 UefiCpuPkg: Update SmmCpuFeatureLib pass XCODE5 tool chain
https://bugzilla.tianocore.org/show_bug.cgi?id=849

In V2, use "mov rax, strict qword 0" to replace the hard code db.

1. Use lea instruction to get the address instead of mov instruction.
2. Use the dummy address as jmp destination, and add the logic to fix up
the address to the absolute address at boot time.

Hao Wu 8491e302e1 UefiCpuPkg: Refine casting expression result to bigger size
There are cases that the operands of an expression are all with rank less
than UINT64/INT64 and the result of the expression is explicitly cast to
UINT64/INT64 to fit the target size.

An example will be:
UINT32 a,b;
// a and b can be any unsigned int type with rank less than UINT64, like
// UINT8, UINT16, etc.
UINT64 c;
c = (UINT64) (a + b);

Some static code checkers may warn that the expression result might
overflow within the rank of "int" (integer promotions) and the result is
then cast to a bigger size.

The commit refines codes by the following rules:
1). When the expression is possible to overflow the range of unsigned int/
int:
c = (UINT64)a + b;

2). When the expression will not overflow within the rank of "int", remove
the explicit type casts:
c = a + b;

3). When the expression will be cast to pointer of possible greater size:
UINT32 a,b;
VOID *c;
c = (VOID *)(UINTN)(a + b); --> c = (VOID *)((UINTN)a + b);

4). When one side of a comparison expression contains only operands with
rank less than UINT32:
UINT8 a;
UINT16 b;
UINTN c;
if ((UINTN)(a + b) > c) {...} --> if (((UINT32)a + b) > c) {...}

For rule 4), if we remove the 'UINTN' type cast like:
if (a + b > c) {...}
The VS compiler will complain with warning C4018 (signed/unsigned
mismatch, level 3 warning) due to promoting 'a + b' to type 'int'.

Add a new instances of the SmmCpuFeaturesLib that is used by
platforms to enable the SMI Transfer Monitor(STM) feature.
This new instance is in the same directory as the default
SmmCpuFeaturesLib instance in order to share source files.

The DSC file is updated to build both SmmCpuFeatureLib
instances and to build two versions of the PiSmmCpuDxeSmm
module using each of the SmmCpuFeatureLib instances.
