assertion.

Fixed linking of modules containing aliases to constant bitcasts. Existing behaviour first tried to replace the aliases with the global that they aliased (rather than the bitcast), causing a crash on an assert because the types didn't match. When this was fixed, it then did the same thing creating the new alias (creating an alias with a different type to its aliasee).
...
Linking modules containing aliases to GEPs is still not quite right. GEPs that are equivalent to bitcasts will be replaced by bitcasts, GEPs that are not will just break. Aliases to GEPs that are not equivalent to bitcasts are horribly broken anyway (it might be worth adding an assert when creating the alias to prevent these being created; they just cause problems later).

Rework InitPreprocessor to use a MacroBuilder class instead of pushing around
...
std::vectors.
- MacroBuilder wraps a raw_ostream so it can easily write to any buffer
supported by raw_ostream.
- MacroBuilder's method take Twines for easy string concatenation (this was done
with sprintf and temporary buffers before).
- Targets still use std::vector as they don't have access to the builder.

Fix a critical bug in 64-bit atomic operation lowering for 32-bit. The results of the cmpxchg8b instructions are being thrown away when it branches back to the top of the checking loop. This means the loop always compares against the old value and this can result in a dead lock.

Change the printing of OR_Deleted overload results to print all the candidates,
...
not just the viable ones. This is reasonable because the most common use of
deleted functions is to exclude some implicit conversion during calls; users
therefore will want to figure out why some other options were excluded.
Started sorting overload results. Right now it just sorts by location in the
translation unit (after putting viable functions first), but we can do better than
that.
Changed bool OnlyViable parameter to PrintOverloadCandidates to an enum for better
self-documentation.
