Whither exceptions

Dale,

Chris would like to turn on -enable-eh rather than
-enable-correct-eh-
support in the llvm testsuite for those targets that support it. The
following patch is intended to turn it on for x86 and ppc. Anton,
Duncan, are you OK with this?

Yes, looks obvious :slight_smile:

If these were visible to end users I would not like exposing sjlj, an
implementation detail; however my understanding is that they aren't.
On the basis that they're intended for use by llvm geeks, I think
either of these is an improvement, except in the second case I think
the default should be target-dependent. Comments?

The -eh-model stuff also looks extremely useful for me.
