This patch adds a new llvm-mca flag named `-print-imm-hex`.

By default, the instruction printer prints immediate operands as decimals. Flag `-print-imm-hex` enables the instruction printer to print those operands in hex.

This patch also adds support for MASM binary and hex literal numbers (example 0FFh, 101b).
Added tests to verify the behavior of the new flag. Tests also verify that masm numeric literal operands are now recognized.

Please let me know if okay to commit.
