Evgeniy Stepanov ae6ebd3af5 Implement __attribute__((internal_linkage)). 
The attrubite is applicable to functions and variables and changes
the linkage of the subject to internal.

This is the same functionality as C-style "static", but applicable to
class methods; and the same as anonymouns namespaces, but can apply
to individual methods of a class.

Following the proposal in
http://lists.llvm.org/pipermail/cfe-dev/2015-October/045580.html

Aaron Ballman 2cfbc00506 Simplifying the mutual exclusion check now that the diagnostics engine knows how to handle Attr objects directly. Updates an associated test case due to the attribute name being properly quoted again.

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.
