alpha: Introduce UMUL_HIGHPART rtx_code [PR113720]
umuldi3_highpart expander does:
if (REG_P (operands[2]))
operands[2] = gen_rtx_ZERO_EXTEND (TImode, operands[2]);
on register_operand predicate, which also allows SUBREG RTX. So,
subregs were emitted without ZERO_EXTEND RTX.
But nowadays we have UMUL_HIGHPART that allows us to fix this
issue while also simplifying the instruction RTX.
PR target/113720
gcc/ChangeLog:
* config/alpha/alpha.md (umuldi3_highpart): Remove expander.
(*umuldi3_highpart_reg): Rename to umuldi3_highpart and
simplify insn RTX using UMUL_HIGHPART rtx_code.
(*umuldi3_highpart_const): Remove.
