Simon Dardis de5ed0c58e Reland "[mips][mt][6/7] Add support for mftr, mttr instructions."
This adjusts the tests to hopfully pacify the
llvm-clang-x86_64-expensive-checks-win buildbot.

Unlike many other instructions, these instructions have aliases which
take coprocessor registers, gpr register, accumulator (and dsp accumulator)
registers, floating point registers, floating point control registers and
coprocessor 2 data and control operands.

For the moment, these aliases are treated as pseudo instructions which are
expanded into the underlying instruction. As a result, disassembling these
instructions shows the underlying instruction and not the alias.

This reverts r310834. It didn't pacify the buildbot, FileCheck is still
crashing.

FileCheck is crashing on in the input file, so reverting again while
I investigate.

This reverts r308023.

The last version of this patch broke one of the expensive checks buildbots,
this version changes the failing test/MC/Mips/mt/invalid.s and other invalid
tests to write the errors to a file and run FileCheck on that, rather than
relying on the 'not llvm-mc ... <%s 2>&1 | Filecheck %s' idiom.

Hopefully this will sarisfy the buildbot.
