Normalize memcmp constant folding results.
The library call simplifier folds memcmp calls with all constant arguments
to a constant. For example:
memcmp("foo", "foo", 3) -> 0
memcmp("hel", "foo", 3) -> 1
memcmp("foo", "hel", 3) -> -1
The folding is implemented in terms of the system memcmp that LLVM gets
linked with. It currently just blindly uses the value returned from
the system memcmp as the folded constant.
This patch normalizes the values returned from the system memcmp to
(-1, 0, 1) so that we get consistent results across multiple platforms.

[analyzer] When invalidating symbolic offset regions, take fields into account.
Previously, RegionStore was being VERY conservative in saying that because
p[i].x and p[i].y have a concrete base region of 'p', they might overlap.
Now, we check the chain of fields back up to the base object and check if
they match.
This only kicks in when dealing with symbolic offset regions because
RegionStore's "base+offset" representation of concrete offset regions loses
all information about fields. In cases where all offsets are concrete
(s.x and s.y), RegionStore will already do the right thing, but mixing
concrete and symbolic offsets can cause bindings to be invalidated that
are known to not overlap (e.g. p[0].x and p[i].y).

Add lldb data formatters for clang classes, starting with SourceLocation.
When installed, instead of getting this:
(lldb) p Tok.Loc
(clang::SourceLocation) $0 = {
(unsigned int) ID = 123582
}
you'll get:
(lldb) p Tok.Loc
(clang::SourceLocation) $4 = "/usr/include/i386/_types.h:37:1" (offset: 123582, file)
This depends on r167629.
