The AArch64 DAIF bits are different for reading (mrs) versus writing (msr).
The bitmask definitions assumed they were the same causing incorrect
results when trying to determine the current interrupt state through
GetInterruptState.
The logic for interpreting the DAIF read data using the csel instruction
was also incorrect and is fixed.
Replaced the magic numbers in DisableInterrupts.S and EnableInterrupts.S

The runtime test whether the compiler supports arithmetic shift of
negative signed numbers currently relies on undefined behavior in C,
which means that all bets are off regarding whether the condition
that follows passes or fails, regardless of whether the compiler in
fact supports arithmetic shift or not.
Relevant quote from ISO C99 (6.5.7/4)
The result of E1 << E2 is E1 left-shifted E2 bit positions; vacated bits
are filled with zeros. If E1 has an unsigned type, the value of the result
is E1 × 2^E2, reduced modulo one more than the maximum value representable
in the result type. If E1 has a signed type and nonnegative value, and
E1 × 2^E2 is representable in the result type, then that is the resulting
value; otherwise, the behavior is undefined.
For historic purposes, let's keep the test in place (although it is doubtful
we actually need it) but rewrite it in a way that prevents compilers from
this century from doing whacky things with it.

The value of EBX must be preserved to follow IA32 cdecl calling convention in the assembly
implementation of AsmFlushCacheLine(). The CPUID instruction modifies the EBX register.
The EBX register value is saved onto the stack before CPUID and restored from the stack
after CPUID.
The update to the inline assembly implementation of AsmFlushCacheLine() changed the location of the
LinearAddress parameter value on the stack. The hardcoded lookup using [esp + 4] is not correct.
Use the parameter name LinearAddress instead of the hard coded [esp + 4] stack location to prevent
this issue from occurring again if there are changes to the inline assembly in the future.

The ARM asm implementation of InternalMathSwapBytes64 () does
interesting things if bit 7 of operand r1 (upper 32 bits of the
input value) is set. After the recursive swap, bit 7 ends up in
the sign bit position, after which it is right shifted with sign
extension, and or'ed with the upper half of the output value.
This means SwapBytes64 (0x00000080_00000000) returns an incorrect
value of 0xFFFFFFFF_80000000.

Fixed issues with X64 clang, and also make StackSwitch push a zero on the new stack to prevent a stack unwind into memory that is no longer valid.

In r11047 Ia32/Thunk.S was modified. However, the current
implemention of Ia32/Thunk.S has contant values in the code
which must be updated if the code is changed.
This change updates those constants for the r11047 change.

Only use X86MemoryFence.c for INTEL and MSFT. MemoryFence is defined
in GccInline.c for GCC.
This change is the same as r10522, but for X64.

Move stack alignment check from CPU specific files into common SwitchStack() function and add VA_END() to SwitchStack().
Fix incorrect syntax for ASM_FUNCTION_REMOVE_IF_UNREFERENCED

It seems for ARM, .align means power of two, so we'd like to use .p2align for more portability.
2. Fix some typos in ARM ProcessorBind.h

2. Add AsmReadMsr() & AsmWriteMsr() for IPF architecture
3. update AsmCpuMisc.s to only support GCC tool chain to avoid symbol collision.

Move IsHexDigit, BufToHexString, HexStringToBuf from BaseLib to MdeModulePkg IfrSupportLib. The reason is:
1) IsHexDigit function provides the logic to check Hex Digit and convert it to Decimal value, which is required by IScsi LUN and HII user input. But this logic is not provided by any functions in MdeLib. So, it can't be deleted. It is moved to IfrSupportLib.
2) BufToHexString function converts a array of buffers to hex string. If the buffer length is less than sizeof (UINT64), it can be directly replaced by UnicodeValueToString(). But HII modules may use BufToHexString to convert the buffers whose length > sizeof (UINT64). For example:
.\MdeModulePkg\Universal\HiiDatabaseDxe\ConfigRouting.c line 201, 1148
.\Universal\SetupBrowserDxe\Setup.c line line 1457, 1503
Like this case, it is not easy to use UnicodeValueToString to replace BufToHexString. So, BufToHexString is still kept. Because such usages are in HII modules, this function is moved to IfrSupportLib.
3) HexStringToBuf is moved to IfrSupportLib. The reason is similar to BufToHexString.

2. Two two new ReadApplicationRegister.c(), ReadControlRegister.c() API together with its related definitions in BaseLib.h
3. Remove prototype of AsmSwitchStackAndBackingStore() in public BaseLib.h, it is supposed to be a worker function for AsmSwitchStack()
