ASan uses GetProcAddress to get the address of malloc so it can patch it. Newer versions of Windows make GetProcAddress initialize the DLL before returning a function pointer into it. That's perfectly reasonable, but ASan needs to finish patching malloc before CRT initialization. So now we roll our own GetProcAddress. Fixes PR24237 Based on a patch by David Major Originally written by David Major as part of: https://hg.mozilla.org/mozilla-central/file/tip/toolkit/xre/WindowsCrtPatch.h llvm-svn: 245377
