Summary:
To limit the number of tests required, only one 64-bit ISA prior to MIPS64 are tested.
rdhwr has been deliberately left without an ISA annotation for now. This is
because the assembler and CodeGen disagree on when the instruction is
available. Strictly speaking, it is only available in MIPS32r2 and
MIPS64r2. However, it is emulated by a kernel trap on earlier ISA's and is
necessary for TLS so CodeGen should emit it on older ISA's too.
Depends on D3697

Summary:
This required a new instruction group representing the 32-bit subset of
MIPS-3 that was available in MIPS32R2.
To limit the number of tests required, only one 32-bit and one 64-bit ISA
prior to MIPS32/MIPS64 are tested.

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:
test/MC/Mips/<isa1>/invalid-<isa2>.s
Test that <isa1> does not support <isa2>'s instructions.
test/MC/Mips/<isa1>/invalid-<isa2>-xfail.s
Things that should be invalid but currently aren't. Will XPASS if any
become invalid.
