(CRIS_DEFAULT_TUNE, CRIS_ARCH_CPP_DEFAULT)
(CRIS_DEFAULT_ASM_ARCH_OPTION): New macros.
(CRIS_CC1_SUBTARGET_SPEC): Change default tuning to use
CRIS_DEFAULT_TUNE.
(CRIS_CPP_SUBTARGET_SPEC): Ditto. Add CRIS_ARCH_CPP_DEFAULT.
(ASM_SPEC): Add sanity-check erroring out when both -march= and
-mcpu= are specified. Pass on either as --march=v32.
(CRIS_ASM_SUBTARGET_SPEC): When neither -march= or -mcpu= are
specified, pass on CRIS_DEFAULT_ASM_ARCH_OPTION.
(CRIS_CPU_V32): New macro.
[!TARGET_CPU_DEFAULT]: Default-define as CRIS_CPU_BASE.
[!TARGET_DEFAULT, TARGET_CPU_DEFAULT == 32]: Move default
TARGET_DEFAULT definition after new TARGET_CPU_DEFAULT definition.
Define v32-adjusted TARGET_DEFAULT.
(CRIS_DEFAULT_CPU_VERSION): Change to TARGET_CPU_DEFAULT from
CRIS_CPU_BASE.
(TARGET_V32): New macro.
(REG_ALLOC_ORDER_V32): New macro.
(HARD_REGNO_MODE_OK): Do not allow larger-than-register-size modes

GENNONACR_REGS and SPEC_GENNONACR_REGS.
(REG_CLASS_NAMES, REG_CLASS_CONTENTS): Adjust for new classes.
(REGNO_REG_CLASS): Give ACR_REGS for CRIS_ACR_REGNUM.
(MODE_CODE_BASE_REG_CLASS): Define, give for OCODE POST_INC
GENNONACR_REGS, BASE_REG_CLASS otherwise.
(REG_CLASS_FROM_LETTER): 'a' is for ACR_REGS.
(REGNO_MODE_CODE_OK_FOR_BASE_P): Define, refusing OCODE POST_INC
for CRIS_ACR_REGNUM.
(PREFERRED_RELOAD_CLASS): Keep ACR_REGS as preferred.
(HARD_REGNO_RENAME_OK): Refuse CRIS_ACR_REGNUM as TO.
(EXTRA_CONSTRAINT): New constraint 'U'.
(TRAMPOLINE_TEMPLATE, TRAMPOLINE_SIZE, INITIALIZE_TRAMPOLINE)
(ASM_OUTPUT_ADDR_DIFF_ELT): Adjust for CRIS v32.
(BASE_OR_AUTOINCR_P): Refuse POST_INC for CRIS_ACR_REGNUM.
(SIMPLE_ADDRESS_P): Remove.
(GO_IF_LEGITIMATE_ADDRESS): Use BASE_OR_AUTOINCR_P, not redundant
SIMPLE_ADDRESS_P. Make one chained if-else, finishing as
non-match after BASE_OR_AUTOINCR_P for TARGET_V32.
(REGISTER_MOVE_COST): Just call the new function
cris_register_move_cost.
(enum cris_pic_symbol_type): Rename cris_gotrel_symbol to
cris_rel_symbol. All users changed.
(REGISTER_NAMES): Replace "pc" with "acr".
