Try to fix more Windows portability issues in sanitizer tests

Add a %stdcxx11 lit substitution for -std=c++11. Windows defaults to
-std=c++14 when VS 2015 is used because the STL requires it. Harcoding
-std=c++11 in the ASan tests actually downgrades the C++ standard level,
leading to test failures.

Relax a FileCheck pattern in use-after-scope-types.cc.

Disable the sanitizer_common OOM tests. They fail on bots with low swap,
and cause other concurrently running tests to OOM.
