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.

Rafael Espindola 3497069784 Switch to the new MingW ABI. 
GCC 4.7 changed the MingW ABI. On the clang side this means that methods now
have the thiscall calling convention by default.

John McCall a97f329869 Template static data members can have weak_odr linkage, not just 
weak linkage.  Also, fix a problem where global weak variables
with non-trivial initializers were getting guard variables, or at
least were checking for them and then crashing.

Nico Weber d75488d010 Correctly set "explicit template instantiation" kind on inner structs of templates whose explicit instantiation is first declared and then defined.
