[ms] [llvm-ml] Add placeholder for llvm-ml, based on llvm-mc
As discussed on the mailing list, I plan to introduce an ml-compatible MASM assembler as part of providing more of the Windows build tools. This will be similar to llvm-mc, but with different command-line parameters. This placeholder is purely a stripped-down version of llvm-mc; we'll eventually add support for the Microsoft-style command-line flags, and back it with a MASM parser. Relanding this revision after fixing ARM-compatibility issues. Reviewers: rnk, thakis, RKSimon Reviewed By: thakis, RKSimon Differential Revision: https://reviews.llvm.org/D72679
