mips-opts.h: New.
* config/mips/mips-opts.h: New.
* config/mips/mips.c (enum mips_r10k_cache_barrier_setting): Move
to mips-opts.h.
(mips_abi, mips_code_readable, mips_r10k_cache_barriee): Remove.
(mips_handle_option): Don't handle OPT_mabi_, OPT_mcode_readable_
or OPT_mr10k_cache_barrier_ here. Access mips_cache_flush_func
via opts pointer.
* config/mips/mips.h (enum mips_code_readable_setting): Move to
mips-opts.h.
(mips_abi, mips_code_readable): Don't declare.
* config/mips/mips.opt (config/mips/mips-opts.h): New
HeaderInclude.
(mabi=): Use Enum and Var.
(mips_abi): New Enum and EnumValue entries.
(mcode-readable=): Use Enum and Var.
(mips_code_readable_setting): New Enum and EnumValue entries.
(mr10k-cache-barrier=): Use Enum and Var.
(mips_r10k_cache_barrier_setting): New Enum and EnumValue entries.
