Move all SHUFP* patterns close to the SHUFP* definitions. Also be

explicit about which subtarget they refer to, and add AVX versions of
the ones we currently don't. Make the mask check more strict, to be
clear it won't be used to match to 256-bit versions!

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.

A value of -1 at a call site tells the personality function that this call isn't
handled by the current function. Since the ResumeInsts are converted to calls to
_Unwind_SjLj_Resume, add a (volatile) store of -1 to its 'call site'.
