module lldbtest.py and refactored the existing test cases to derive from the
abstract base class lldbtest.TestBase.

MOdified the test driver (dotest.py and dotest.pl) to set up additional
PYTHONPATH component for locating the lldbtest module, which sits in the same
directory.

Only actual functions get mangled correctly; I don't know how to fix it for
function pointers yet. Thanks to John McCall for the hint.

Also, mangle anonymous tag types. I don't have a suitable testcase yet; I have
a feeling that that's going to need support for static locals, and I haven't
figured out exactly how MSVC's scheme for mangling those works.

expression command to use this IR transformer when
conversion to DWARF fails, and wired conversion to
DWARF to always fail (well, we don't generate any
DWARF...)

declarations for implicit default constructors, copy constructors,
copy assignment operators, and destructors. On a "simple" translation
unit that includes a bunch of C++ standard library headers, we
generate relatively few of these implicit declarations now:

  4/159 implicit default constructors created
  18/236 implicit copy constructors created
  70/241 implicit copy assignment operators created
  0/173 implicit destructors created

And, on this translation unit, this optimization doesn't really
provide any benefit. I'll do some more performance measurements soon,
but this completes the implementation work for <rdar://problem/8151045>.

The COPY instruction is intended to replace the target specific copy

INSERT_SUBREG instructions in MachineFunctions. It won't we used in a selection

new basic blocks, and if used as a function argument, that can cause call frame
setup / destroy pairs to be split across a basic block boundary. That prevents
us from doing a simple assertion to check that the pairs match and alloc/
dealloc the same amount of space. Modify the assertion to only check the
amount allocated when there are matching pairs in the same basic block.
