pull .ll and .bc writing out of the ASTConsumer destructors into some top
level code in clang. This is a cleanup, but does implement "-o" for
-emit-llvm. One effect of this is that "clang foo.c -emit-llvm" will now
emit into foo.ll instead of stdout. Use "clang foo.c -emit-llvm -o -" or
"clang < foo.c -emit-llvm" to get the old behavior.

Added some skeleton code for performing "assume" on symbols: e.g. assume($0 != 0).
This action will add constraints to the possible values of a symbol.
Still needs to be debugged.

Change the key of CGRecordLayouts from being an llvm type* to being a decl*. LLVM
Type*'s can change as types are refined, so we can't use them as a stable key in
the map. Decls don't change, so use them instead.
This patch was written by Anders, but he's too shy to commit it himself :)

Created ValueStateManager, a full-blown class to manage the states
created for GRConstants. Moved instances of ValueManager and SymbolManager
inside this class. The goal is to gradually separate more of the state
management from the state transformation.

- ccc now creates object files without an extension.

minor tweak to anders patch: (only) ocu vectors support splatting, but
ocu vectors should not treat bitcasts from int <-> vector as a splat

Cleanup previous patch (based on feedback from Ted).
Since this behavior is useful for most classes, we might consider adding a simple 3 method class that implements the behavior. Ted said that Boost has such a class.

For ObjCAtCatchStmt, removed field 'NextAtCatchStmt' (which referenced the next @catch)
and put the the next ObjcAtCatchStmt* as part of SubExprs. This fixes a bug with
iterating over the children of ObjcAtCatch, where the next @catch was not
properly being iterated over as a child.
Altered serialization of ObjCAtCatchStmt to reflect this new layout of
its subexpressions, and fixed an ownership issue with the next @catch not
being serialized as an owned pointer.

Fix two rewriter bugs with @catch.

Sema::ActOnInstanceMessage is generally doing bad things with typedefs, but

getAsPointerType() not static_cast<PointerType*> to get the pointee. This
