LoongArch: Split vec_selects of bottom elements into simple move
For below pattern, can be treated as a simple move because floating point
and vector share a common register on loongarch64.
(set (reg/v:SF 32 $f0 [orig:93 res ] [93])
(vec_select:SF (reg:V8SF 32 $f0 [115])
(parallel [
(const_int 0 [0])
])))
gcc/ChangeLog:
* config/loongarch/lasx.md (vec_extract<mode>_0):
New define_insn_and_split patten.
gcc/testsuite/ChangeLog:
* gcc.target/loongarch/vect-extract.c: New test.
