i386: Remove mulv2si emulated sequence for TARGET_SSE2 [PR109797]
Remove mulv2si emulated sequence for TARGET_SSE2 and enable
only native PMULLD instruction for TARGET_SSE4_1. Ideally, the
vectorization for TARGET_SSE2 should depend on more precise cost
estimation (the PR contains patch for ix86_multiplication_cost),
but even with patched cost function the runtime regression
was not fixed.
PR target/109797
gcc/ChangeLog:
* config/i386/mmx.md (mulv2si3): Remove expander.
(mulv2si3): Rename insn pattern from *mulv2si.
