Subject: [PATCH v2 0/10] Cleanup & new features for compiler*.h and bug.h

This patch set is a dependency of the generic red-black tree patch set, which
I have now split up into three smaller sets.

The major aim of this patch set is to cleanup compiler-gcc*.h and improve the
manageability of of compiler features at various versions (when they are
broken, etc.), and to cleanup & add some needed features to bug.h.

compiler-gcc*.h
o Introduce GCC_VERSION - (e.g., gcc 4.7.1 becomes 40701)
o Reorder all features based upon the version introduced (readability)
o Change all version checks to use GCC_VERSION
o Remove redundant __linktime_error

bug.h
o Improve BUILD_BUG_ON(expr) - Will now generate a compile-time error and in
  gcc-4.4+, also emits an error message containing the expression that failed.
o Add BUILD_BUG_ON_MSG(expr, msg) - Like BUILD_BUG_ON, except that you can
  specify the error message that is emitted (again, gcc-4.4+).
o Add BUILD_BUG_ON_INTERNAL(expr, fn, msg) - contains a generic implementation
  of BUILG_BUG_ON{_MSG}.
o Finally, the implementations of BUILD_BUG{,_ON,_ON_MSG} is consolidated,
  eliminating duplicate code.
