George Koehler f1304e1a3c Use extended mnemonics and ha16/lo16.
Remove wrong comment: that's a right shift, not a left shift.

George Koehler 5b69777647 Rename our pseudo-opcode 'la' to 'li32'.
GNU as has "la %r4,8(%r3)" as an alias for "addi %r4,%r3,8", meaning
to load the address of the thing at 8(%r3).  Our 'la', now 'li32',
makes an addis/ori pair to load an immediate 32-bit value.  For
example, "li32 r4,23456789" loads a big number.

David Given 80cb6ba927 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.
