(sbbl x, x) sets the registers to 0 or ~0.  Combined with two's complement arithmetic, we can fold
the intermediate AND and the ADD into a single SUB.

This fixes <rdar://problem/8449754>.

For ObjCPropertyDecls in class extensions, use the class extension as the lexical DeclContext for newly created
ObjCMethodDecls.  Further, use the location of the new property declaration as the location of new ObjCMethodDecls
(if they didn't previously exist).

This fixes more of the issues reported in <rdar://problem/7410145>.

instead of calling lower_bound or upper_bound directly.

This cleans up the search logic a bit because {lower,upper}_bound compare
LR->start by default, and it is usually simpler to search LR->end.

Funnelling all searches through one function also makes it possible to replace
the search algorithm with something faster than binary search.

I am unable to write a test for this case, help is solicited, though...
What I did is to tickle the code in the debugger and verify that we do the right thing.

This necessitates the passing of CmpValue around,
