Changes in v4:
o Squash a minor commit (per Borislav Petkov)
o Change some comment text (per Borislav Petkov)
o Add some acks

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

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.), add some needed features to bug.h and clean that up as
well.

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) - now generates compile-time error post-gcc-4.4
o Remove duplicate error messages in some cases.
o Introduce BUILD_BUG_ON_MSG and clean up the implementations of the
BUILD_BUG* macros.
