db8552c834 [mips][microMIPS] MicroMIPS 16-bit unconditional branch instruction B
Implement microMIPS 16-bit unconditional branch instruction B.

Implemented 16-bit microMIPS unconditional instruction has real name B16, and
B is an alias which expands to either B16 or BEQ according to the rules:
b 256 --> b16 256 # R_MICROMIPS_PC10_S1
b 12256 --> beq $zero, $zero, 12256 # R_MICROMIPS_PC16_S1
b label --> beq $zero, $zero, label # R_MICROMIPS_PC16_S1

00e08fcaa0 Canonicalize header guards into a common format.
Add header guards to files that were missing guards. Remove #endif comments
as they don't seem common in LLVM (we can easily add them back if we decide
they're useful)

Changes made by clang-tidy with minor tweaks.

37ef65b9c1 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.

ec3199f675 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.
