Summary:
A small number of instructions are rejected with the wrong error message.
These have been placed in a separate test for now. There seems to be some
parsing quirk that triggers when these instructions are disabled.
Depends on D3571

Summary:
These processors will only be available for the integrated assembler at
first (CodeGen will emit a fatal error saying they are not implemented).
The intention is to work through the existing instructions and correctly
annotate the ISA they were added in so that we have a sufficiently good
base to start MIPS64r6 development. MIPS64r6 removes/re-encodes certain
instructions and I believe it is best to define ISA's using set-union's
as far as possible rather than using set-subtraction.

GAS doesn't actually accept these particular cases.
The mnemonic without the trailing 'v' still supports two-operand aliases.

Summary:
The pattern sltu $r1, $r2, $imm is found in handwritten assembly which
is just a shorthand version of sltui $r1, $r2, $imm.

Summary:
Also renamed non-portable register names (e.g. $t2) so that we don't end up
with a different encoding for what appears to be an equivalent instruction.

This enables TableGen to generate an additional two operand
matcher for our shift_rotate_imm and shift_rotate_reg class of instructions.
The tests were also updated so that they include now encoding information
for all affected instructions.

Summary:
Where those ISA's are not currently supported, the test is run with the smallest
superset of that ISA.
Some instructions are valid but don't pass yet. These have been placed in the
valid-xfail.s's which will XPASS if _any_ instruction starts working.
The valid.s's do not verify the encoding yet. There are also no tests checking that instructions from neighbouring ISA's are not accepted.
