Reid Kleckner d85f7010cc [windows] Implement GetProcAddress internally to avoid initializing the CRT 
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

AddressSanitizer RT
================================
This directory contains sources of the AddressSanitizer (ASan) runtime library.

Directory structure:
README.txt       : This file.
Makefile.mk      : File for make-based build.
CMakeLists.txt   : File for cmake-based build.
asan_*.{cc,h}    : Sources of the asan runtime library.
scripts/*        : Helper scripts.
tests/*          : ASan unit tests.

Also ASan runtime needs the following libraries:
lib/interception/      : Machinery used to intercept function calls.
lib/sanitizer_common/  : Code shared between various sanitizers.

ASan runtime currently also embeds part of LeakSanitizer runtime for
leak detection (lib/lsan/lsan_common.{cc,h}).

ASan runtime can only be built by CMake. You can run ASan tests
from the root of your CMake build tree:

make check-asan
