C++ PATCH for `throw'

[Paul Burchard]

It looks to my untrained eye like case STMT_EXPR: in tsubst_copy() might
still be blurring the boundaries between tree manipulation and RTL
generation phases.

(If I understand correctly, that's the boundary you're working to
clarify, both to enable more-global analysis, and also to allow
different middle-ends (e.g. doc generators) to be plugged in place of
RTL generation.  Sorry if I'm way off base here...despite the clarity of
ir.texi, I still don't understand how this is supposed to happen on the
API level.)
