[WebAssembly] Initial SIMD128 support.
...
Kicks off the implementation of wasm SIMD128 support (spec:
https://github.com/stoklund/portable-simd/blob/master/portable-simd.md ),
adding support for add, sub, mul for i8x16, i16x8, i32x4, and f32x4.
The spec is WIP, and might change in the near future.

[WebAssembly] Add AsmString strings for most instructions.
...
Mangling type information into MachineInstr opcode names was a temporary
measure, and it's starting to get hairy. At the same time, the MC instruction
printer wants to use AsmString strings for printing. This patch takes the
first step, starting the process of adding AsmStrings for instructions.
