Turns out Apple's hi16/ha16 exactly match my ha16/has16, so renamed

accordingly. (Memo to self: read the docs *before* doing the work.)

Signed vs unsigned lower halves of powerpc fixups are now handled by having two
...
assembler directives, ha16() and has16(), for the upper half; has16() applies
the sign adjustment. .powerpcfixup is now gone, as we generate the relocation
in ha*() instead. Add special logic to the linker for undoing and redoing the
sign adjustment when reading/writing fixups. Tests still pass.

Revert change; addis/ori requires different handling to addis/lwz due to ori's

payload being unsigned while lwz's payload is signed.
