Fix PR82941 and PR82942 by adding proper vzeroupper generation on SKX.
Add X86_TUNE_EMIT_VZEROUPPER to indicate if vzeroupper instruction should
be inserted before a transfer of control flow out of the function. It is
turned on by default unless we are tuning for KNL. Users can always use
-mzeroupper or -mno-zeroupper to override X86_TUNE_EMIT_VZEROUPPER.

The current rs6000 rtx_cost for comparisons against 0 is very high if
TARGET_ISEL && !TARGET_MFCRF, much higher than for reg-reg comparisons,
much higher than a load of 0 and such a reg-reg-comparison. This leads
to infinite recursion in CSE (see PR81288).
This patch removes the too-high cost, also simplifying this code.

combine: Don't split insns if half is unused (PR82621)
If we have a PARALLEL of two SETs, and one half is unused, we currently
happily split that into two instructions (albeit the unused one is
useless). Worse, as PR82621 shows, combine will happily merge this
insn into I3 even if some intervening insn sets the same register
again, which is wrong.
This fixes it by not splitting PARALLELs with REG_UNUSED notes. It
all is handled fine by combine in that case; just the "single set
that is unused" case isn't handled properly.
This also results in better code: combine will now actually throw
away the unused SET. (It still won't do that in an I3).
