Ted Kremenek f8e4b48b3d Tweak location of diagnostic for -Wunreachable-code
test due to recent changes to the CFG.  The
diagnostic is somewhat in the wrong place, but
the -Wunreachable-code diagnostic needs to be
revamped anyway since most of the diagnostics
in this test case are redundant.

Anders Carlsson af7534f084 Get rid of the "functions declared 'noreturn' should have a 'void' result type" warning.
The rationale behind this is that it is normal for callback functions to have a non-void return type
and it should still be possible to mark them noreturn. (JavaScriptCore is a good example of this).

Zhongxing Xu a396e617b5 Always add CallExpr as block-level expression. Inline-based interprocedural
analysis needs this.

Mike Stump 04c6851cd6 Speed up compilation by avoiding generating exceptional edges from
CallExprs as those edges help cause a n^2 explosion in the number of
destructor calls.  Other consumers, such as static analysis, that
would like to have more a more complete CFG can select the inclusion
of those edges as CFG build time.

This also fixes up the two compilation users of CFGs to be tolerant of
having or not having those edges.  All catch code is assumed be to
live if we didn't generate the exceptional edges for CallExprs.
