Previously, the assertions in PointerIntPair would try to calculate the value
(1 << NumLowBitsAvailable); the inferred type here is 'int', so if there were
more than 31 bits available we'd get a shift overflow.

Also, add a rudimentary unit test file for PointerIntPair.

It has a lot of them with complex types. C++11 really shines here.

The integrated assembler now works for ppc. Since this was the last use of the
bg/p predicate and Hal says that it is now dead, drop the predicate too.

After hitting the malloc() breakpoint on FreeBSD our top frame is actually
an inlined function malloc_init.

  * frame #0: 0x0000000800dcba19 libc.so.7`malloc [inlined] malloc_init at malloc.c:5397
    frame #1: 0x0000000800dcba19 libc.so.7`malloc(size=1024) + 9 at malloc.c:5949
    frame #2: 0x00000000004006e5 test_step_out_of_malloc_into_function_b_with_dwarf`b(val=1) + 37 at main2.cpp:29

Add a heuristic to keep stepping out until we come to a non-malloc caller,
before checking if it is our desired caller from the test code.

This is a straightfoward replacement, it makes debugging a little
easier.

This has no functional impact.

A freebsd issue with rm prevents '[g]make clean' from working if $(DSYM)
is empty (fts_open(3) fails if passed an empty argument).

To work around this, simplify the clean target by using three separate
rm invocations: one for the common files, one for the case of non-empty
$(DYLIB_NAME), and one for non-empty $(DSYM).

Issue diagnosed (and reported to FreeBSD) by John Wolfe.

[C++11] Adding an iterator_range accessor for parameter declarations to the CaptureDecl class; however, the only usage of the iterators cannot be converted to using the range yet. This change is for consistency with other Decls exposing parameters.

The target was marking SIGN_EXTEND as Custom because it wanted to optimize
certain sign-extended shifts.  In all other respects the extension is Legal,
so it'd be better to do the optimization in PerformDAGCombine instead.

No functional change intended.
