[cfe-commits] [PATCH] Instantiate dependent attributes in template code.

This patch modifies Sema::InstantiateAttrs so that attributes in
template code are properly instantiated; the previous behavior was to
clone them. The main motivation for the patch are thread safety
attributes, which make extensive use of expressions.
A new method named instantiateFromTemplate is now generated for all
attributes. The behavior of this method is identical to clone() for
all arguments except ExprArgument and VariadicExprArgument;
expression arguments are instantiated rather than cloned.
Features still on the todo list are:
(1) Instantiate type arguments as well as expressions. This will
affect attributes other than thread-safety, so I wanted to get
feedback before implementing it.
(2) Move handling of the aligned attribute to the new mechanism.
