    x86: Properly handle USE_VECTOR_FP_CONVERTS/USE_VECTOR_CONVERTS

    Check TARGET_USE_VECTOR_FP_CONVERTS or TARGET_USE_VECTOR_CONVERTS when
    handling avx_partial_xmm_update attribute.  Don't convert AVX partial
    XMM register update if vector packed SSE conversion should be used.

            * config/i386/i386-features.c (remove_partial_avx_dependency):
            Check TARGET_USE_VECTOR_FP_CONVERTS and TARGET_USE_VECTOR_CONVERTS
            before generating vxorps.
