Martin Storsjö 42f74e8249 [llvm] Rename StringRef _lower() method calls to _insensitive() 
This is a mechanical change. This actually also renames the
similarly named methods in the SmallString class, however these
methods don't seem to be used outside of the llvm subproject, so
this doesn't break building of the rest of the monorepo.

Eric Astor 6b70a83d9c [ms] [llvm-ml] Add support for .radix directive, and accept all radix specifiers 
Add support for .radix directive, and radix specifiers [yY] (binary), [oOqQ] (octal), and [tT] (decimal).

Also, when lexing MASM integers, require radix specifier; MASM requires that all literals without a radix specifier be treated as in the default radix. (e.g., 0100 = 100)

Relanding D87400, now with fewer ms-inline-asm tests broken!

Eric Astor ee2c0f76d7 [ms] [llvm-ml] Add a draft MASM parser 
Summary:
Many directives are unavailable, and support for others may be limited.

This first draft has preliminary support for:
    - conditional directives (including errors),
    - data allocation (unsigned types up to 8 bytes, and ALIGN),
    - equates/variables (numeric and text),
    - and procedure directives (without parameters),
as well as COMMENT, ECHO, INCLUDE, INCLUDELIB, PUBLIC, and EXTERN. Text variables (aka text macros) are expanded in-place wherever the identifier occurs.

We deliberately ignore all ml.exe processor directives.

Prominent features not yet supported:
    - structs
    - macros (both procedures and functions)
    - procedures (with specified parameters)
    - substitution & expansion operators

Conditional directives are complicated by the fact that "ifdef rax" is a valid way to check if a file is being assembled for a 64-bit x86 processor; we add support for "ifdef <register>" in general, which requires adding a tryParseRegister method to all MCTargetAsmParsers. (Some targets require backtracking in the non-register case.)
