* config/xtensa/xtensa.c (order_regs_for_local_alloc): Order the
coprocessor registers before floating-point registers.
* config/xtensa/xtensa.h (REG_ALLOC_ORDER): Adjust register numbers
to account for a previously removed register.
(SPEC_REG_FIRST, SPEC_REG_LAST, SPEC_REG_NUM, COUNT_REGISTER_REGNUM):
Delete unused macros.
