Store inheritance paths after CastExprs instead of inside them.
...
This takes some trickery since CastExpr has subclasses (and indeed,
is abstract).
Also, smoosh the CastKind into the bitfield from Expr.
Drops two words of storage from Expr in the common case of expressions
which don't need inheritance paths. Avoids a separate allocation and
another word of overhead in cases needing inheritance paths. Also has
the advantage of not leaking memory, since destructors for AST nodes are
never run.

Correct -ftrapv to trap on errors, instead of calling the
...
__overflow_handler entrypoint that David Chisnall made up.
Calling __overflow_handler is not part of the contract of
-ftrapv provided by GCC, and should never have been checked
in in the first place.
According to:
http://permalink.gmane.org/gmane.comp.compilers.clang.devel/8699
David is using this for some of arbitrary precision integer stuff
or something, which is not an appropriate thing to implement on
this.
