i386: Emulate MMX sse_cvtpi2ps with SSE

Emulate MMX sse_cvtpi2ps with SSE2 cvtdq2ps, preserving upper 64 bits of
destination XMM register.  Only SSE register source operand is allowed.

PR target/89021
* config/i386/sse.md (sse_cvtpi2ps): Changed to
define_insn_and_split.  Also allow TARGET_MMX_WITH_SSE.  Add
SSE emulation.
