Daniel Sanders 7e51fe19d5 [mips][msa] Added support for matching splati from normal IR (i.e. not intrinsics) 
Updated some of the vshf since they (correctly) emit splati's now

Akira Hatanaka 2c544d8ed5 [mips] Make "b" (unconditional branch) a pseudo. "b" is an assembly idiom, which is 
equivalent to "beq $zero, $zero, offset".

Akira Hatanaka e2a39e7532 [mips] Delete unnecessary InstAliases. Also, clear some of the InstAlias' 
EmitAlias flag and have MipsInstPrinter::printAlias print the aliases.

Akira Hatanaka 34a32c0b87 [mips] Replace usages of register classes with register operands. Also, remove 
unnecessary jalr InstAliases in Mips64InstrInfo.td and add the code to print
jalr InstAliases in MipsInstPrinter::printAlias.

Akira Hatanaka 5973e8371a [mips] Define "bal" as a pseudo instruction. Also, fix bug in the InstAlias that 
turns "bal" into "bgezal".

Akira Hatanaka 0b40014d4e [mips] Delete register print method MipsInstPrinter::printCPURegs that is not 
needed. The generic method printOperand will do.

No functionality change.

Akira Hatanaka 53900e5124 [mips] Print instructions "beq", "bne" and "or" using assembler pseudo 
instructions "beqz", "bnez" and "move", when possible.

beq $2, $zero, $L1 => beqz $2, $L1
bne $2, $zero, $L1 => bnez $2, $L1
or  $2, $3, $zero  => move $2, $3

Jack Carter 9c1a027fe8 This patch that sets the EmitAlias flag in td files 
and enables the instruction printer to print aliased 
instructions. 

Due to usage of RegisterOperands a change in common 
code (utils/TableGen/AsmWriterEmitter.cpp) is required 
to get the correct register value if it is a RegisterOperand.

Jack Carter 873c724b4a This patch tackles the problem of parsing Mips 
register names in the standalone assembler llvm-mc.

Registers such as $A1 can represent either a 32 or
64 bit register based on the instruction using it.
In addition, based on the abi, $T0 can represent different
32 bit registers.


The problem is resolved by the Mips specific AsmParser 
td definitions changing to work together. Many cases of
RegisterClass parameters are now RegisterOperand.
