Hans Wennborg c9bd88e681 Remove the -cxx-abi command-line flag. 
This makes the C++ ABI depend entirely on the target: MS ABI for -win32 triples,
Itanium otherwise. It's no longer possible to do weird combinations.

To be able to run a test with a specific ABI without constraining it to a
specific triple, new substitutions are added to lit: %itanium_abi_triple and
%ms_abi_triple can be used to get the current target triple adjusted to the
desired ABI. For example, if the test suite is running with the i686-pc-win32
target, %itanium_abi_triple will expand to i686-pc-mingw32.

Hans Wennborg 9125b08b52 Update tests in preparation for using the MS ABI for Win32 targets 
In preparation for making the Win32 triple imply MS ABI mode,
make all tests pass in this mode, or make them use the Itanium
mode explicitly.

Rafael Espindola 925213b0fa Add 'not' to commands that are expected to fail. 
This is at least good documentation, but also opens the possibility of
using pipefail.

Jordan Rose 04a94d1442 Provide a fixit to static_cast for reinterpret_casts within a class hierarchy. 
The suggestion was already in the text of the note; this just adds the
actual fixit and the appropriate test cases.

John McCall cda8083309 Warn about attempts to reinterpret_cast between two types that are 
hierarchy-related at a possibly nonzero offset.
