Fix a theoretical bug when ParseCompoundStatement() returns StmtError.

ParseCompoundStatement() currently never returns StmtError, but if it did,
Sema would keep the __finally scope on its stack indefinitely.  Explicitly
add an error callback that clears it.

Nico Weber [Mon, 9 Mar 2015 02:47:59 +0000 (02:47 +0000)]
Warn when jumping out of a __finally block via continue, break, return, __leave.

Since continue, break, return are much more common than __finally, this tries
to keep the work for continue, break, return O(1).  Sema keeps a stack of active
__finally scopes (to do this, ActOnSEHFinally() is split into
ActOnStartSEHFinally() and ActOnFinishSEHFinally()), and the various jump
statements then check if the current __finally scope (if present) is deeper
than then destination scope of the jump.

The same warning for goto statements is still missing.

This is the moral equivalent of MSVC's C4532.
