Eli Friedman 1bc0fed9a5 Fix codegen for conditionals with incommpatible pointer types. Code
that causes this isn't really correct, but if we're going to accept 
this, it should come up with a consistent AST.

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

Use this method to insert implicit casts for case statements from their 
operand type to the condition type of the switch.  This fixes a crash on
test/CodeGen/statements.c, reported by Eli Friedman.

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!
