Initial implementation of __atomic_is_lock_free.  The input is the size of an atomic type rather than an atomic type itself just to save some implementation pain; I can change that if it seems worthwhile.

I think this is the last hook needed for <atomic> besides defines for ATOMIC_CHAR_LOCK_FREE and friends.

almost identically to the C++ personality function. In particular, it uses
"null" as a "catch-all" value.

The comparison of two vectors should return a signed result. hasIntegerRepresentation() used to always return false for vectors, but since it was changed, it also
changed the return type of a compare of two unsigned vectors to be unsigned. This patch removes the check for hasIntegerRepresentation since its not needed and returns the appropriate signed type.
I added a new test case and updated exisiting test cases that assumed an unsigned result.

top-level declarations that occurred inside an ObjC container.

This is useful to keep track of such decls otherwise when e.g. a function
is declared inside an objc interface, it is not passed to HandleTopLevelDecl
and it is not inside the DeclContext of the interface that is returned.

is evaluated at the stop point to decide whether we should proceed with
the stopping.

Also add SBWatchpont::SetCondition(const char *condition) to set condition
programmatically.
