darwin.h: Set MAX_LONG_TYPE_SIZE to 32.
* config/rs6000/darwin.h: Set MAX_LONG_TYPE_SIZE to 32.
* config/rs6000/rs6000.c (rs6000_emit_move): In Darwin-
specific codegen, eliminate a register copy.
(print_operand_address): Add support for Darwin's lo16(constant)
syntax.
(rs6000_machopic_legitimize_pic_address): Fix darwin-specific
generation of addresses within very large data objects.
(s8bit_cint_operand): New.
* config/rs6000/rs6000.md: Remove "iu" reference for 750/7400.
Move "mtjmpr" to correct functional unit for 750/7400/7450.
Add imul2 and imul3 insn types for multiplication by 16- and
8-bit constants.
Change tablejump patterns to strongly discourage using LR
rather than CTR.
Add %lo16 patterns for Darwin loads and stores.
