tag decl after it has been completed

Chris Lattner 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.

Chris Lattner a65e1f3b31 Move promoteExprToType from being a static method in SemaExpr.cpp to being 
a method named ImpCastExprToType in Sema.

operand type to the condition type of the switch.  This fixes a crash on

Steve Naroff f727faf2ed Explicitly set the string literal type from "char *" to "constant array of char". 
At this point, I am fairly certain the front-end is correct. Unfortunately, the back-end is still unhappy.

That said, I've commented out the two lines in globalinit.c that are causing problems.

Chris, please have a look...thanks!

Oliver Hunt aefc8fd415 Support initalisers for more than just int-typed static variables.
