Predrag Rudic 25d4f93740 Reland "MIPS[64] Implementation of MSA instructions on builtin simulator"
This is reland of 3e0bf580e8
Original change's description:
> This commit is a step toward enabling test-run-wasm-simd tests for MIPS.
> 36 of those were failing in V8 builtin simulator because some instructions
> were not implemented.  Also there are minor fixes to some of the already
> implemented instructions.
>
> This commit has only 32-bit implementation. After review I will add
> 64-bit version.
