2016-03-24[asan] Intercept all Heap* related imports from ucrtbase.dllReid Kleckner
ucrtbase.dll appears to be built with some kind of cross-module inlining, because there are calls to imported Heap* routines sprinkled throughout the code. This inlining defeats our attempts to hotpatch malloc, _malloc_base, and related functions. Failing to intercept an allocation or deallocation results in a crash when the program attempts to deallocate or reallocate memory with the wrong allocator. This change patches the IAT of ucrtbase.dll to replace the addresses of the imported Heap* functions with implementations provided by ASan. We don't globally intercept the win32 Heap* functions because they are typically used by system DLLs that run before ASan initializes. Eventually, we may want to intercept them, but for now I think this is the minimal change that will keep ASan stable.

2015-08-18[windows] Implement GetProcAddress internally to avoid initializing the CRTReid Kleckner
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.

2015-06-19CMake: Stop using LLVM's custom parse_arguments. NFCFilipe Cabecinhas
Summary: Use CMake's cmake_parse_arguments() instead. It's called in a slightly different way, but supports all our use cases. It's in CMake 2.8.8, which is our minimum supported version. CMake 3.0 doc (roughly the same. No direct link to 2.8.8 doc): http://www.cmake.org/cmake/help/v3.0/module/CMakeParseArguments.html?highlight=cmake_parse_arguments Since I was already changing these calls, I changed ARCH and LIB into ARCHS and LIBS to make it more clear that they're lists of arguments.
