 - 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).

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

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

wasn't happening!  Have it produce target assembler and assemble that
instead.
