Benjamin Kramer 29c2b4330c Add support for __attribute__((hot)) and __attribute__((cold)). ...

Currently cold functions are marked with the "optsize" attribute in CodeGen
so they are always optimized for size.  The hot attribute is just ignored,
LLVM doesn't have a way to express hotness at the moment.
