Diego Novillo 5f2b1ce21e [PATCH] Generate cold attribute for functions marked __atribute__((cold)) 
This removes a FIXME in CodeGenModule::SetLLVMFunctionAttributesForDefinition.
When a function is declared cold we can now generate the IR attribute in
addition to marking the function to be optimized for size.

I tried adding a separate CHECK in the existing test, but it was
failing.  I suppose CHECK matches one line exactly once?  This would be
a problem if the attributes are listed in a different order, though they
seem to be sorted.

Bill Wendling c33fc4c004 Modify the tests to use attribute group references instead of listing the 
function attributes.

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.
