x86/AVX512: improve generated code for bit-wise negation of vectors of integers
NOT on vectors of integers does not require loading a constant vector of
all ones into a register - VPTERNLOG can be used here (and could/should
be further used to carry out other binary and ternary logical operations
which don't have a special purpose instruction).

* config/i386/sse.md (ternlogsuffix): New.
(one_cmpl<mode>2): Don't force CONSTM1_RTX into a register when
AVX512F is in use.
(<mask_codefor>one_cmpl<mode>2<mask_name>): New.
