* config/mips/mips.h (processor_type): Removed PROCESSOR_24K, add

PROCESSOR_24KC and PROCESSOR_24KF.
* config/mips/mips.c (mips_cpu_info_table): Add processor names
and aliases for 4kec/4kem/4kep/24kec/24kef/24kex/34kc/34kf/34kx.
(mips_rtx_cost_data): Add costs for the 24kc.
* config/mips/mips.md ("cpu"): Remove 24k, add 24kc and 24kf.
* config/mips/24k.md: Remove references to 24k and replace with
uses of 24kc/24kf in the appropriate reservations.
* doc/invoke.texi (MIPS Options): Updated.
