Summary:
Added support for the following instructions:
CACHEE, LBE, LBUE, LHE, LHUE, LWE, LLE, LWLE, LWRE, PREFE,
SBE, SHE, SWE, SCE, SWLE, SWRE, TLBINV, TLBINVF
This required adding some infrastructure for the EVA ASE.

Summary:
This patch remaps the assembly idiom 'move' to 'or' instead of 'daddu' or
'addu'. The use of addu/daddu instead of or as move was highlighted as a
performance issue during the analysis of a recent 64bit design. Originally
move was encoded as 'or' by binutils but was changed for the r10k cpu family
due to their pipeline which had 2 arithmetic units and a single logical unit,
and so could issue multiple (d)addu based moves at the same time but only 1
logical move.
This patch preserves the disassembly behaviour so that disassembling a old style
(d)addu move still appears as move, but assembling move always gives an or

Summary:
These AssemblerPredicate's are unnecessary and actually make some instructions unusable when assembling pre-MIPS32 ISAs.
For example, this was causing the IAS to reject the 'j' instruction for MIPS I-V.

Summary:
This adds a MipsInstAlias which expands to XORi $reg,$reg,imm. For example, "xor $6, 0x3A" should be expanded to "xori $6, $6, 58".
This should work for all MIPS ISAs.

Summary:
These ISA's didn't add any instructions so they are almost identical to
Mips32r2 and Mips64r2. Even the ELF e_flags are the same, However the ISA
revision in .MIPS.abiflags is 3 or 5 respectively instead of 2.
