selectImpl is able to select G_FSQRT when we set bank for vector
operands to fprb. Add detailed tests. 
Note: G_FSQRT is generated from llvm-ir intrinsics llvm.sqrt.*,
and at the moment MIPS is not able to generate this intrinsic for
vector type (some targets generate vector llvm.sqrt.* from calls
to a builtin function).
__builtin_msa_fsqrt_<format> will be transformed into G_FSQRT
in legalizeIntrinsic and selected in the same way.
