    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.
