i386: Fix up cvtsd2ss splitter [PR104502]
The following testcase ICEs, because AVX512F is enabled, AVX512VL is not,
and the cvtsd2ss insn has %xmm0-15 as output operand and %xmm16-31 as
input operand. For output operand %xmm16+ the splitter just gives up
in such case, but for such input it just emits vmovddup which requires
AVX512VL if either operand is EXT_REX_SSE_REG_P (when it is 128-bit).
The following patch fixes it by treating that case like the pre-SSE3
output != input case - move the input to output and do everything on
the output reg which is known to be < %xmm16.
