8b6af8a2a9 LSR wants to split the landing pad's critical edge. Let it do it, but use the
proper function to do it.

5fbe5e783e Some autoconf tests use module level inline asm to test compiler's handling of
.cfi_startproc. e.g. libffi:

 $ cat confopt.c 
asm (".cfi_startproc\n\t.cfi_endproc");

int main () { return 0; }

Teach MC / dwarf emission to handle these cfi directives which essentially
create an empty frame.

3bde6fe0df Introduce a pass to insert vzeroupper instructions to avoid AVX to
SSE transition penalty. The pass is enabled through the "x86-use-vzeroupper"
llc command line option. This is only the first step (very naive and
conservative one) to sketch out the idea, but proper DFA is coming next
to allow smarter decisions. Comments and ideas now and in further commits
will be very appreciated.
