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.
