by my recent GVN improvement. Looking through a single layer of
PHI nodes when attempting to sink GEPs, we need to iteratively
look through arbitrary PHI nests.

situations where on the common path an API can return a pointer to some direct
memory, but which on an exceptional path may need to return a pointer to a
temporary struct.

I added these instructions recently but I have no idea where these "1"
values in the NextCycles field came from. As far as I can tell now,
these instruction stages are clearly intended to overlap.

- I'm leaving MachO.h, because I believe it has external consumers, but I would really like to eliminate it (we have stylistic disagreements with one another).

independent information on the Mach object format, and move some stuff from
MachObjectWriter.cpp there.

- Double the vector's capacity when growing to avoid unneeccesary reallocation.
- Do the reallocation with realloc(3) which can expand the memory in place.

GNU ld/PECOFF accepts but ignores them below;
--version-script
--export-dynamic
--rpath
FIXME: autoconf should be aware of them.

The path also holds a reference to the root node, and that allows important
iterator accessors like start() and stop() to have no conditional code. (When
the compiler is clever enough to remove it.)

work when llvm-gcc is really dragonegg (which can output IR with -S
but not -c). Yes, dragonegg supports objective-c++ (poorly though).

the output of this test. Since it was producing bitcode, that clearly
wasn't happening! Have it produce target assembler and assemble that
instead.
