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.

Fix for PR5967: Make const-marking for LLVM globals correct for cases requiring run-time initialization, and emit run-time initializers aggresively to avoid ordering issues with deferred globals. llvm-svn: 92976

extern void* foo;
static void* const a = foo;
void* bar() { return a; }
Mangle static variables with an extra name to distinguish them from non-static variables in the same TU. Fixes PR5966 for real this time; also reverts r92911, which had a incorrect fix. llvm-svn: 94352

Account for calling convention specifiers in function definitions in IR test cases Several tests wouldn't pass when executed on an armv7a_pc_linux triple due to the non-default arm_aapcs calling convention produced on the function definitions in the IR output. Account for this with the application of a little regex. Patch by Ying Yi. llvm-svn: 240971
