Don't gimple fold ymm-version vblendvpd/vblendvps/vpblendvb w/o TARGET_AVX2

Since 256-bit vector integer comparison is under TARGET_AVX2,
and gimple folding for vblendvpd/vblendvps/vpblendvb relies on that.
Restrict gimple fold condition to TARGET_AVX2.

gcc/ChangeLog:

PR target/106704
* config/i386/i386-builtin.def (BDESC): Add
CODE_FOR_avx_blendvpd256/CODE_FOR_avx_blendvps256 to
corresponding builtins.
* config/i386/i386.cc (ix86_gimple_fold_builtin):
Don't fold IX86_BUILTIN_PBLENDVB256, IX86_BUILTIN_BLENDVPS256,
IX86_BUILTIN_BLENDVPD256 w/o TARGET_AVX2.

gcc/testsuite/ChangeLog:

* gcc.target/i386/pr106704.c: New test.
