i386: Use ix86_output_ssemov for MMX TYPE_SSEMOV
There is no need to set mode attribute to XImode since ix86_output_ssemov
can properly encode xmm16-xmm31 registers with and without AVX512VL.
PR target/89229
* config/i386/i386.c (ix86_output_ssemov): Handle MODE_DI,
MODE_V1DF and MODE_V2SF.
* config/i386/mmx.md (MMXMODE:*mov<mode>_internal): Call
ix86_output_ssemov for TYPE_SSEMOV. Remove ext_sse_reg_operand
check.
