Driver: Turn the default value for -fmath-errno into a proper target hook and disable it by default on more platforms.

For now -fno-math-errno is the default on BSD-derived platforms (Darwin,
DragonFlyBSD, FreeBSD, NetBSD, OpenBSD). If the default is not right for
your platform, please yell. I only verified the result with the default
compilers on Darwin and FreeBSD.

-fpack-struct's handling has changed in CC1 (one of only two flags that needed changing) because the driver treats "-fpack-struct" as a boolean flag, and CC1 (did) treat it as an option with a separated value.

This change causes -fpack-struct=X to be forwarded correctly to -fpack-struct=X instead of erroneously to "-fpack-struct X"

Refine analyzer diagnostics by adding an expression "cone-of-influence" to reverse track interesting
values through interesting expressions.  This allows us to map from interesting values in a caller
to interesting values in a caller, thus recovering some precision in diagnostics lost from IPA.

declared in a subclass has consistent parameter types with a method
having the same selector in a superclass performs a significant number
of lookups into the class hierarchy. In the example in
<rdar://problem/11004361>, we spend 4.7% of -fsyntax-only time in
these lookups.

Optimize away most of the calls to this routine
(Sema::CompareMethodParamsInBaseAndSuper) by first checking whether we
have ever seen *any* method with that selector (using the global
selector table). Since most selectors are unique, we can avoid the
cost of this name lookup in many cases, for a 3.3% speedup.
