[mips][mips64r6] Added mul/mulu/muh/muhu Summary: The 'mul' line of the test is temporarily commented out because it currently matches the MIPS32 mul instead of the MIPS32r6 mul. This line will be uncommented when we disable the MIPS32 mul on MIPS32r6.

[mips][mips64r6] Add b[on]vc Summary: This required me to implement the disassembler for MIPS64r6 since the encodings are ambiguous with other instructions. This in turn revealed a few assembly/disassembly bugs which I have fixed. * da[ht]i only take two operands according to the spec, not three. * DecodeBranchTarget2[16] correctly handles wider immediates than simm16 * Also made non-functional change to DecodeBranchTarget and DecodeBranchTargetMM to keep implementation style consistent between them. * Difficult encodings are handled by a custom decode method on the most general encoding in the group. This method will convert the MCInst to a different opcode if necessary. DecodeBranchTarget is not currently the inverse of getBranchTargetOpValue so disassembling some branch instructions emit incorrect output. This seems to affect branches with delay slots on all MIPS ISA's. I've left this bug for now and temporarily removed the check for the immediate on bc[12]eqz/bc[12]nez in the MIPS32r6/MIPS64r6 tests. jialc and jic crash the disassembler for some reason. I've left these instructions commented out for the moment.

# Branches have some unusual encoding rules in MIPS32r6 so we need to test:
# rs == 0
# rs != 0
# rt == 0
# rt != 0
# rs < rt
# rs == rt

[mips][mips64r6] b(ge|lt)zal are not available on MIPS32r6/MIPS64r6 and bal is a normal instruction Summary: b(ge|lt)zal have been removed in MIPS32r6/MIPS64r6. However, bal (an alias for 'bgezal $zero, $offset') still remains with the same encoding it had prior to MIPS32r6/MIPS64r6. Updated the MipsNaCLELFStreamer, and MipsLongBranch to correctly handle the MIPS32r6/MIPS64r6 BAL instruction in addition to the existing BAL_BR pseudo. No changes were required to the CodeGen test that looks for BAL (test/CodeGen/Mips/longbranch.ll) since the new instruction has the same syntax.

[mips][mips64r6] Add b[on]vc Summary: This required me to implement the disassembler for MIPS64r6 since the encodings are ambiguous with other instructions. This in turn revealed a few assembly/disassembly bugs which I have fixed. * da[ht]i only take two operands according to the spec, not three. * DecodeBranchTarget2[16] correctly handles wider immediates than simm16 * Also made non-functional change to DecodeBranchTarget and DecodeBranchTargetMM to keep implementation style consistent between them. * Difficult encodings are handled by a custom decode method on the most general encoding in the group. This method will convert the MCInst to a different opcode if necessary. DecodeBranchTarget is not currently the inverse of getBranchTargetOpValue so disassembling some branch instructions emit incorrect output. This seems to affect branches with delay slots on all MIPS ISA's. I've left this bug for now and temporarily removed the check for the immediate on bc[12]eqz/bc[12]nez in the MIPS32r6/MIPS64r6 tests. jialc and jic crash the disassembler for some reason. I've left these instructions commented out for the moment.

[mips][mips64r6] Replace m[tf]hi, m[tf]lo, mult, multu, dmult, dmultu, div, ddiv, divu, ddivu for MIPS32r6/MIPS64. Summary: The accumulator-based (HI/LO) multiplies and divides from earlier ISA's have been removed and replaced with GPR-based equivalents. For example: div $1, $2 mflo $3 is now: div $3, $1, $2 This patch disables the accumulator-based multiplies and divides for MIPS32r6/MIPS64r6 and uses the GPR-based equivalents instead. Renamed expandPseudoDiv to insertDivByZeroTrap to better describe the behaviour of the function. MipsDelaySlotFiller now invalidates the liveness information when moving instructions to the delay slot. Without this, divrem.ll will abort since %GP ends up used before it is defined.

It happens because there is an instruction with a wider immediate that would have matched if the NotMips32r6 predicate were true. I have some WIP to improve the message but it affects most error messages for removed/re-encoded instructions on MIPS32r6/MIPS64r6 and should therefore be a separate commit.
