History
Daniel Sanders 0ebf8e82e0 Add ability to emit internal instruction representation to CodeGen assembly output. 
Summary:
This patch re-uses the implementation of 'llvm-mc -show-inst' and makes it
available to llc as 'llc -asm-show-inst'.

This is necessary to test parts of MIPS32r6/MIPS64r6 without resorting to
'llc -filetype=obj' tests. For example, on MIPS32r2 and earlier we use the
'jr $rs' instruction for indirect branches and returns. On MIPS32r6, we no
longer have 'jr $rs' and use 'jalr $zero, $rs' instead. The catch is that,
on MIPS32r6, 'jr $rs' is an alias for 'jalr $zero, $rs' and is the preferred
way of writing this instruction. As a result, all MIPS ISA's emit 'jr $rs' in
their assembly output and the assembler encodes this to different opcodes
according to the ISA.

Using this option, we can check that the MCInst really is a JR or a JALR by
matching the emitted comment. This removes the need for a 'llc -filetype=obj'
test.
