Series i386: Properly encode xmm16-xmm31/ymm16-ymm31 for vector move | expand

Commit Message

H.J. Lu Feb. 15, 2020, 3:26 p.m. UTC 
There is no need to set mode attribute to XImode since ix86_output_ssemov
can properly encode xmm16-xmm31 registers with and without AVX512VL.

gcc/

	PR target/89229
	* config/i386/i386.md (*movsi_internal): Call ix86_output_ssemov
	for TYPE_SSEMOV.  Remove ext_sse_reg_operand and TARGET_AVX512VL
	check.

gcc/testsuite/

	PR target/89229
	* gcc.target/i386/pr89229-4a.c: New test.
	* gcc.target/i386/pr89229-4b.c: Likewise.
	* gcc.target/i386/pr89229-4c.c: Likewise.
