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'.

Update the MSR header file of Skylake processor according to Intel(R) 64
and IA-32 Architectures Software Developer's Manual, Volume 3, September
2016, Chapter 35 Model-Specific-Registers (MSR), Section 35.15.
Summary of incompatible changes:
1. MSR (address 38EH) IA32_PERF_GLOBAL_STAUS has been renamed to
IA32_PERF_GLOBAL_STATUS
Typo 'STAUS' has been fixed in SDM.

Update MSR header files of processors (excluding Goldmont and Skylake
processors) according to Intel(R) 64 and IA-32 Architectures Software
Developer's Manual, Volume 3, September 2016, Chapter 35
Model-Specific-Registers (MSR).
Summary of incompatible changes:
General:
1. MSR (address 38EH) IA32_PERF_GLOBAL_STAUS in processor-specific header
files has been removed or renamed to IA32_PERF_GLOBAL_STATUS
Typo 'STAUS' has been fixed in SDM.
If the MSR definition is the same with architectural MSR, we remove it.
Otherwise, we rename the MSR.
2. MSRs (address starting from 400H) MSR_MC{X}_{XXX} (like MSR_MC4_STATUS)
in processor-specific header files have been removed or renamed to
IA32_MC{X}_{XXX} (like IA32_MC4_STATUS)
Register name change from 'MSR_MC{X}_{XXX}' to 'IA32_MC{X}_{XXX}' in SDM.
If the MSR definition is the same with architectural MSR, we remove it.
Otherwise, we rename the MSR.
Please note that for those MSRs still have name like 'MSR_MC{X}_{XXX}' in
SDM are still kept in processor-specific header files.
HaswellMsr.h:
1. MSR (address C80H) IA32_DEBUG_FEATURE has been removed
Register name change from 'IA32_DEBUG_FEATURE' to 'IA32_DEBUG_INTERFACE'
in SDM.
Since the MSR definition is the same with architectural MSR, we remove it.
SandyBridgeMsr.h:
1. MSR (address 391H) MSR_UNC_PERF_GLOBAL_CTRL, name change for bit fields
0:3
Bit description change from 'Core {X} select' to 'Slice {X} select' for
bit 0:3 in SDM.
SilvermontMsr.h:
1. MSR (address 2AH) MSR_EBL_CR_POWERON, structure definition changed
Bit description for this MSR is totally changed in SDM, we modify the
structure definition to align with it.
XeonDMsr.h:
1. MSRs (address 630H to 632H) MSR_PKG_C8_RESIDENCY, MSR_PKG_C9_RESIDENCY
and MSR_PKG_C10_RESIDENCY have been removed
Those 3 MSRs are not defined for this processor in SDM, we remove them.
