After this change, `check-asan-dynamic` should pass on x86_64 MinGW target, using the llvm-mingw toolchain. The following is a list of issues fixed: * `asan_str_test.cpp`: Exclude unintercepted functions on MinGW. * `asan_test.cpp`: Work around regex limitation of gtest on Windows, which only affects MinGW target because `long double` has different size to `double`. * `TestCases/Windows/report_after_syminitialize.cpp`: Added build command specifically for MinGW. * Other tests: Mark XFAIL for various reasons. Some of them need further investigation. Differential Revision: https://reviews.llvm.org/D147059
