e8eafdb676 [mips][msa] Implemented copy_[us].d intrinsic. 
This intrinsic is lowered into equivalent copy_s.w instructions during
legalization.

c8a1fa77a7 [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

9c0f5ed594 [mips][msa] Added MSA.txt to describe instruction selection quirks. 
This file contains notes about the instruction selection for MSA. For example,
it notes that ilvl.d is cannot be selected because ilvev.d covers the same
cases and is selected instead of ilvl.d.
