[PATCH] D28525: [compiler-rt] Use macros to simplify weak alias for Windows and add some documentation.

[Reid Kleckner via Phabricator via llvm-commits]

rnk added a comment.

Defining a cross-platform weak mechanism seems like a great idea, even if we can only use it when we have default implementations. It greatly simplify our Windows porting efforts. Adding new weak functions is one of the more common ways to break the WinASan build.
