Defer saving the altivec registers until we need to access them (like
how arm defers saving the VFP registers). This prevents a SIGILL on a
G3 cpu when code throws a C++ exception.

Turns out I botched the previous commit. While making the %o7 + 8 bit2019-02-03T15:24:17Zketteniskettenis@openbsd.org2019-02-03T15:24:17Zurn:sha1:904ff9a2689ab293783b1642bea8f3b81bc01042
consistent across the various low-level interfaces that handle the
instruction pointer, reality turns out to be a bit more subtle.
On SPARC, DWARF2 uses r15 (which maps to %o7) as the return address column.
This means that we should not add/subtract 8 when it reads/updates the
register state while processing DWARF2 instructions. That in turn means
that getIP() and setIP() should not have been changed in my previous commit.
