  testsuite: Add ABIs to the test matrix; unify tests across ABIs
  
  This eliminates all the *_win32.c tests in favor of the tests they were
  branched from, and expands test coverage to run many more tests on
  stdcall, thiscall, and fastcall.
  
  This same mechanism also supports testing any other target that has
  multiple ABIs.
