[X86][MC][bugfix] Report error for mismatched modifier in inline asm and remove function getX86SubSuperRegisterOrZero
```
MCRegister getX86SubSuperRegister*(MCRegister Reg, unsigned Size,
bool High = false);
```
A strange behavior of the functions `getX86SubSuperRegister*` was
introduced by llvm-svn:145579: The returned register may not
match the parameters when a 8-bit high register is required.
And llvm-svn: 175762 refined the code and dropped the comments, then we
knew nothing happened there from the code :-(
These two functions are only called with `Size=8` and `High=true` in two places.
One is in `X86FixupBWInsts.cpp` for liveness of registers and the other is in
`X86AsmPrinter.cpp` for inline asm.
For the first one, we provide an alternative in this patch.
For the second one, the strange behaviour caused a bug that an erorr was not reported for mismatched modifier.
```
void f() {
char x;
asm volatile ("mov %%ah, %h0" :"=r"(x)::"%eax", "%ebx", "%ecx", "%edx", "edi", "esi");
}
```
```
$ gcc -S test.c
error: extended registers have no high halves
```
```
$ clang -S test.c
no error
```
so we fix the bug in this patch.
`getX86SubSuperRegister` is just a wrapper of `getX86SubSuperRegisterOrZero` with a `assert`.
I belive we should remove the latter.

The culprit is that InEC is initialized before Inbound, and Inbound's
initialization happens through a call to openFileForRead. However, the
typical initialization order warnings don't fire; so the behavior was:
Inbound is initialized correctly by openFileForRead; then it's reset to
whatever initializer value (0 originally).
A fix is to move Inbound's decl upfront. I'd still prefer initializing
it to something - and -1 seems like a more appropriate value (it causes
a fail-fast rather than a hang due to trying to read from a
valid-looking but unopen fd).

The iterative approach is the obvious one of building a work queue and

as they would have been called during a recursive traversal.

Add CFI integer types normalization
This commit adds a new option (i.e.,
`-fsanitize-cfi-icall-normalize-integers`) for normalizing integer types
as vendor extended types for cross-language LLVM CFI/KCFI support with
other languages that can't represent and encode C/C++ integer types.
Specifically, integer types are encoded as their defined representations
(e.g., 8-bit signed integer, 16-bit signed integer, 32-bit signed
integer, ...) for compatibility with languages that define
explicitly-sized integer types (e.g., i8, i16, i32, ..., in Rust).
``-fsanitize-cfi-icall-normalize-integers`` is compatible with
``-fsanitize-cfi-icall-generalize-pointers``.
This helps with providing cross-language CFI support with the Rust
compiler and is an alternative solution for the issue described and
alternatives proposed in the RFC
https://github.com/rust-lang/rfcs/pull/3296.
For more information about LLVM CFI/KCFI and cross-language LLVM
CFI/KCFI support for the Rust compiler, see the design document in the

AMDGPU/MC: Refactor decoders. Rework decoders for float immediates

e.g. OPW128 could be used for RegisterOperands that use v2f64 v4f32

require that immediate is decoded using 64, 32 and 16 bit immediate

decodeOperand_<RegClass> only provides width for register decoding,
introduce decodeOperand_<RegClass>_Imm<ImmWidth> that also provides
width for immediate decoding.
Refactor RegisterOperands:
- decoders get _Imm<ImmWidth> suffix in some cases
- removed unused RegisterOperands defined via multiclass
- use different RegisterOperand in a few places, new RegisterOperand's
decoder corresponds to the number of bits used for operand's encoding
Refactor decoder functions:
- add asserts for the size of encoding that will be decoded
- regroup them according to the method of decoding
decodeOperand_<RegClass> (register only, no immediate) decoders can now
create immediate of consistent size, use it for better diagnostic of
