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.

Changed profiling method for ImmutableMap to once again just use its

unique ImutAVLTree* for profiling.
Modified ImutAVLTree:
(1) changed ComputeHash() to ComputeDigest() and
(2) changed Profile() to use the computed digest and
(3) modified insertion of IMutAVLTree into the FoldingSet owned by
the ImutAVLTreeFactory object to use profiling instead of computing
a direct hash. This fixes a bug where our abuse of the FoldingSet would
not work when the FoldingSet was resized.
