Allow more PowerPC instructions in relocations.
...
I need this for relocations in lis/lfd pairs. I add lfd along with
addi, lfs, lha, stfs, stfd to the list.

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.

Add assembler support for fixing up arbitrary oris/addi pairs of instructions;
...
this should allow oris/lwz constant value loads, which will save an opcode.

Eliminate the RELOH2 relocation, as it never worked --- the address would be
...
calculated incorrectly because of overflow errors.
Replace it with an extended RELOPPC relocation which understands addis/ori
pairs; add an la pseudoop to the assembler which generates these and the
appropriate relocation. Make good.

Fix a whole pile of issues related to the failed attempt to increase
...
the number of types of relocation possible in the object file. (Now,
hopefully, working.)
Also change the object serialiser/deserialiser to never try to read or
write raw structures; it's way safer this way and we don't need the
performance boost any more.

of a segment. It also uses the "object" library to read and write ACK-
