Hi:
This patch is to fix a typo in my last patch [1].
[1] https://gcc.gnu.org/pipermail/gcc-patches/2020-August/551982.html
Bootstrap is ok, gcc regression test hosted on CLX for i386/x86-64
backend is ok.
Ok for trunk?
gcc/ChangeLog:
PR target/96755
* config/i386/sse.md:
Hi:
Since This testcase is used to check generation of AVX512 vector
comparison, scan-assembler for vmov instruction could be deleted, also
-mprefer-vector-width=512 is added to avoid impact of different
default arch/tune of GCC.
Sorry for the inaccuracy of the testcase.

According to Intel SDM, VPMOVQB xmm1/m16 {k1}{z}, xmm2 has 16-bit
memory_operand instead of 128-bit one which exists in current
implementation. Also for other vpmov instructions which have
memory_operand narrower than 128bits.
Bootstrap is ok, regression test for i386/x86-64 backend is ok.

Hi:
Sorry for Incomplete test for my last patch at
https://gcc.gnu.org/pipermail/gcc-patches/2020-October/555948.html.
This patch should fix invalid address introduced by special memory constraint.
Bootstrap is ok, regression test is ok for make check
Hi:
For inline asm, there could be an operand like (not (mem:)), it's
not a valid operand for normal memory constraint.

Those two define_insns have same pattern, and
_load_mask would always be matched since it show up
earlier in the md file, and it may lose some opportunity in
pass_reload since _load_mask only have constraint "0C"
for operand2, and "v" constraint in _vblendm would never
be matched.

Update patch.
There are a lot of avx512 define_insns which lack corresponding memory
broadcast version, i only add *avx512f_mul3_bcst and
*avx512dq_mul3_bcst in this patch.

Hi:
For struct initialization, when it fits in a TImode, gcc will use
pinsr insn which causes poor codegen described in PR93897 and PR96562.
Bootstrap is ok, regression test is ok for i386/x86-64 backend.
Ok for trunk?
