Hans Wennborg d7895aca99 [MS ABI] Error instead of generating bad vftables for certain virtual hierarchies (PR18967)
Erroring out until we fix the bug means we don't have to keep chasing down
this same miscompile in a bunch of different places.

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.

Reid Kleckner 340ad862d9 [ms-abi] Always generate complete constructors in the Microsoft C++ ABI
Fixes PR18435, where we generated a base ctor instead of a complete
ctor, and so failed to construct virtual bases when constructing the
complete object.

Peter Collingbourne 66f82e68c3 [ms-cxxabi] Move CodeGenVTables::needsVTTParameter to ItaniumCXXABI.
This function only makes sense there.  Eventually it should no longer
be part of the CGCXXABI interface, as it is an Itanium-specific detail.
