This patch adds a new preprocessor extension ``#pragma clang final`` which enables warning on undefinition and re-definition of macros. The intent of this warning is to extend beyond ``-Wmacro-redefined`` to warn against any and all alterations to macros that are marked `final`. This warning is part of the ``-Wpedantic-macros`` diagnostics group. Reviewed By: aaron.ballman Differential Revision: https://reviews.llvm.org/D108567
