mips-protos.h (mips_dangerous_for_la25_p): Declare.
* config/mips/mips-protos.h (mips_dangerous_for_la25_p): Declare.
(mips_preferred_reload_class): Declare.
* config/mips/mips.h (DANGEROUS_FOR_LA25_P): Replace with function.
(EXTRA_CONSTRAINT): Update accordingly.
(PREFERRED_RELOAD_CLASS): Use mips_preferred_reload_class.
* config/mips/mips.c (mips_dangerous_for_la25_p): New function.
(mips_preferred_reload_class): New function. Prefer LEA_REGS if
mips_dangerous_for_la25_p.
(mips_secondary_reload_class): Use LEA_REGS rather than GR_REGS
if mips_dangerous_for_la25_p.
