Increasingly the .fail.cpp tests are written using -verify, making them
sensitive to the exact diagnostics generated by the compiler. To prevent
additional diagnostics from being generated, and causing the tests to fail,
this patch removes the warning flags when compiling those tests.
llvm-svn: 276208
Summary: Detecting `-Wno-<warning>` flags can be tricky with GCC (See https://gcc.gnu.org/onlinedocs/gcc/Warning-Options.html). This patch adds a special `addWarningFlagIfSupported(<flag>)` method to the test compiler object that can be used to add warning flags. The goal of this patch is to help get the test suite running with more warnings.

Automatically enable clang verify whenever the '-verify-ignore-unexpected' flag
is supported.
Failure tests are run using verify if they contain one or more "expected-*"
diagnostics tags. Otherwise they are run normally.

Summary:
This patch allows the use of LIT's ShTest format in the libc++ test suite. ShTests have the suffix '.sh.cpp'. It also introduces a series of other changes. These changes are:
- More functionality including parsing test metadata has been moved into LIT.
- LibcxxTestFormat now supports multi-part suffixes.
- the `CXXCompiler` functionality has been used to shrink the size of LibcxxTestFormat.
- The recursive loading of the site config has been turned into `libcxx.test.config.loadSiteConfig` so it can be used with libc++abi.
- Temporary files are now created in the build directory of libc++. This follows how it is down in ShTest.
- `not.py` was added as a utility executable that mirrors the functionality of LLVM's `not` executable.
- The first ShTest test was added under test/libcxx/double_include.sh.cpp

This patch addresses some comments on http://reviews.llvm.org/D7019.
- Move compiler.py to test/libcxx from test/libcxx/test.
- Make CXXCompiler.target None by default.
- Use `{}` instead of `dict()` to initialize an empty dict.
- Pass the -fsanitize options to both the compile and link commands.
