Note that I seriously doubt that this perticular construct is useful,
though: it's a pointer in an alternate address space pointing into
unqualified address space.

this does is reconstruct the type for structs and arrays if the type
wouldn't be compatible otherwise.
The assertion about packing in the struct type reconstruction code
sucks, but I don't see any obvious way to fix it. Maybe we need a general
utility method to take a list of types and alignments and try to construct an
unpacked type if possible?

bit-field initialization; ugly code, X86-only, but it works, at least
for basic stuff. Separates/adds union initialization; currently disabled,
though, because the struct/array code needs modifications to support
elements of the wrong type.
Fixes PR2381 and PR2309 with the bit-field initialization. And NetHack
compiles and appears to work with a few tweaks (to work around the lack
of transparent_union support, and clang being a bit strict about
conflicting declarations).

implement bitfield codegen (although I don't envy the person who
implements it). This also prevents a crash on code like that from PR2309
(it's still broken, but it fails more gracefully).

This is a fairly mechanical/large change. As a result, I avoided making any changes/simplifications that weren't directly related. I did break two Analysis tests. I also have a couple FIXME's in UninitializedValues.cpp. Ted, can you take a look? If the bug isn't obvious, I am happy to dig in and fix it (since I broke it).

lib dir and move all the libraries into it. This follows the main
llvm tree, and allows the libraries to be built in parallel. The
top level now enforces that all the libs are built before Driver,
but we don't care what order the libs are built in. This speeds
up parallel builds, particularly incremental ones.
