A new test case in PR middle-end/19583 showed me that I wasn't
handling TRY_CATCH_EXPR with EH_FILTER_EXPR quite right in
block_may_fallthru.  A TRY_CATCH_EXPR with an EH_FILTER_EXPR is used
to only permit certain exceptions.  It handles a throw(TYPE)
expression in C++, in which the programmer has declared that any
exception other than TYPE should cause an unhandled exception error.

I was thinking the same thing when the testcase came though. I also tested a similar patch on powerpc-darwin with no regressions also.
