As shift = (OpCode >> 5) & 0x3, shift will never be larger than 0x3,
so the comparison between shift and 0x12 will always be false. The right
shift type of ASR is 0x2.

GCC8 reported it with the following warning:
ArmPkg/Library/ArmDisassemblerLib/ArmDisassembler.c: In function 'DisassembleArmInstruction':
ArmPkg/Library/ArmDisassemblerLib/ArmDisassembler.c:397:30: error: bitwise
comparison always evaluates to false [-Werror=tautological-compare]
if ((OpCode & 0x0db00000) == 0x03200000) {
This condition tries to be true for both the immediate and the register
version of the MSR instruction. They get identified inside the if-block
using the variable I, which contains the value of bit 25.
The problem with the comparison reported by GCC is that the
bitmask excludes bit 25, while the value requires it to be set to one:
0x0db00000: 0000 11011 0 11 00 00 0000 000000000000
0x03200000: 0000 00110 0 10 00 00 0000 000000000000
^
So the solution is to just don't require that bit to be set, because
it gets checked later using 'I', which results in the following value:
0x01200000: 0000 00010 0 10 00 00 0000 000000000000

AsciiStrCat() is deprecated / disabled under the
DISABLE_NEW_DEPRECATED_INTERFACES feature test macro.
The "Str" variable serves no particular purpose in the MRegList() and
ThumbMRegList() functions; replace it with the pointed-to "mMregListStr" /
"mThumbMregListStr" global variable (as appropriate), so that the new
AsciiStrCatS() calls are as clear as possible.
