rs6000: Support [u]mul<mode>3_highpart for vector
This patch is to make Power10 newly introduced vector
multiply high (part) instructions exploited in vectorized
loops, it renames existing define_insns as standard pattern
names. It depends on that patch which enables vectorizer
to recog mul_highpart.
gcc/ChangeLog:
* config/rs6000/vsx.md (mulhs_<mode>): Rename to...
(smul<mode>3_highpart): ... this.
(mulhu_<mode>): Rename to...
(umul<mode>3_highpart): ... this.
* config/rs6000/rs6000-builtin.def (MULHS_V2DI, MULHS_V4SI,
MULHU_V2DI, MULHU_V4SI): Adjust.
gcc/testsuite/ChangeLog:
* gcc.target/powerpc/mul-vectorize-3.c: New test.
* gcc.target/powerpc/mul-vectorize-4.c: New test.
