re PR target/70300 (ICE: in extract_constrain_insn, at recog.c:2190 (insn does not satisfy its constraints) with -mtune=amdfam10 -mavx512bw)

PR target/70300
* config/i386/i386.md (cvtsd2ss splitter): Unpack in destination
instead of source if operands[1] is xmm16 and above and
!TARGET_AVX512VL.  Use avx512f_vec_dupv16sf_1 instead of
vec_interleave_lowv4sf if we need to unpack xmm16 and above.

* gcc.target/i386/pr70300.c: New test.
