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.

Whack a bunch of tests in CodeGenCXX to work on ARM (using ARM ABI). Batch 1 of 3 or so. llvm-svn: 132945 2011-06-14 06:51:21 +08:00			`// CHECK: define linkonce_odr {{.*}} @_ZN2X0C1Ev`
