Push a new region for the try block and propagate execution counts
through it. This ensures that catch statements get a region counter
distinct from the try block's counter.

This patch changes cc1 option -fprofile-instr-generate to an enum option
-fprofile-instrument={clang|none}. It also changes cc1 options
-fprofile-instr-generate= to -fprofile-instrument-path=.
The driver level option -fprofile-instr-generate and -fprofile-instr-generate=
remain intact. This change will pave the way to integrate new PGO
instrumentation in IR level.

The catch keyword isn't really part of a region, so it's fairly
meaningless to extend into it. This was usually harmless, but it could
crash when catch blocks involved macros in strange ways.
