increasingly prevailing case to the point that new features

This required a little bit of reshuffling with exceptions
because a check was assuming that ObjCNonFragileABI was

obnoxious to do.
Most, though, it involved a perl script to translate a ton
of test cases.
Mostly no functionality change for driver users, although
there are corner cases with disabling language-specific
exceptions that we should handle more correctly now.

ANSI C requires that a call to an unprototyped function type succeed
...
if the definition has a non-variadic prototype with compatible
parameters. Therefore, the default rule for such calls must be to
use a non-variadic convention. Achieve this by casting the callee to
the function type with which it is required to be compatible, unless
the target specifically opts out and insists that unprototyped calls
should use the variadic rules. The only case of that I'm aware of is
the x86-64 convention, which passes arguments the same way in both
cases but also sets a small amount of extra information; here we seek
to maintain compatibility with GCC, which does set this when calling
an unprototyped function.
Addresses PR10810 and PR10713.

The eh.selector intrinsic isn't used anymore. Replace the check here with a

check for the landingpad instruction instead. This check looks at each of the
clauses in the landingpad instruction. If it's a catch clause, it compares the

each value in the filer to see if any have the prefix.

Throw the switch to convert clang to the new exception handling model!
...
This model uses the 'landingpad' instruction, which is pinned to the top of the
landing pad. (A landing pad is defined as the destination of the unwind branch
of an invoke instruction.) All of the information needed to generate the correct
exception handling metadata during code generation is encoded into the
landingpad instruction.
The new 'resume' instruction takes the place of the llvm.eh.resume intrinsic
call. It's lowered in much the same way as the intrinsic is.
