This allows us to pass the pt_regs pointer in to these functions
ready for tail-calling the abort handler.

Re-jig the CPU abort helpers to take the PC/PSR in r4/r5 rather
than r2/r3.

Require all callers of abort macros to specify the registers to be
used. This improves the documentation at the callsites as to which
registers are being used by this assembly code.

Initial git repository build. I'm not bothering with the full history,
even though we have it. We can create a separate "historical" git
archive of that later if we want to, and in the meantime it's about
3.2GB when imported into git - space that would just make the early
git days unnecessarily complicated, when we don't have a lot of good
infrastructure for it.
Let it rip!
