579a05d767 Fix PR2049, updating Eli's patch that fixes to mainline. This produces incorrect 
code, but the codegen doesn't crash.  I'll file a bugzilla for the AST being wrong.

f3bc75afcf Since isComplexType() no longer returns true for _Complex integers, the code 
generator needs to call isAnyComplexType().  This fixes PR1960.

a21ad8058a Fix several bugs in array -> pointer decomposition. 
First, we got several CVR propagation cases wrong, which Eli pointed
out in PR2039.

Second, we didn't propagate address space qualifiers correctly, leading
to incorrect lowering of code in CodeGen/address-space.c.

Third, we didn't uniformly propagate the specifier in the array to the
pointer ("int[restrict 4]" -> "int *restrict").

This adds an ASTContext::getArrayDecayedType member that handles the 
non-trivial logic for this seemingly simple operation.

b5eda6253b 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.
