Support for ARM9
* config/arm/arm.c (all_procs): Add arm9 and arm9tdmi.

* config/arm/arm.md (attr cpu): Add arm9.
General scheduling changes
* config/arm/arm.c (MAX_INSNS_SKIPPED): Delete.

(arm_override_options): If generating hard floating point code for
the FPA, emit code for version 3.
When optimizing for space, don't synthesize constants.
Reword several flags based on the requested processor and optimization
level.
(use_return_insn): New argument iscond, all callers changed.  Don't
use a return insn if it will be conditional and that would be
expensive; eg on StrongARM.
(arm_adjust_cost): Anti- and output- dependencies normally have no
cost.
(load_multiple_sequence): Newer ARMs don't benefit from ldm if
the sequence is short.
(final_prescan_insn): Use max_insns_skipped instead of
MAX_INSNS_SKIPPED.  Note whether we will make a return instruction
conditional, and aviod this if it would be expensive.

Rewrite to better describe ARM8, 9 and StrongARM.
* config/arm/arm.md (*movhi_insn_littleend): Make op0 predicate
s_register_operand.
