mips.h (GO_IF_LEGITIMATE_ADDRESS): Don't accept large register offsets; let LEGITIMIZE_ADDRESS load it into a register.

* mips.h (GO_IF_LEGITIMATE_ADDRESS): Don't accept large
register offsets; let LEGITIMIZE_ADDRESS load it into a register.
(LEGITIMIZE_ADDRESS): Use plus_constant to avoid (plus (reg) (const_int 0))
* mips.md (call_internal3c): New pattern for -mips16 -mlong-calls.
