Hi Lang

(Note this depends on http://reviews.llvm.org/D15943).

This extends the header pad generation we have to also support the -headerpad *size* option.

Similarly to ld64, if both -headerpad_max_install_names and -headerpad are passed, then we take the maximum of the two.

Comments welcome.

Thanks,
Pete
