* config/arm/arm-modes.def: Add new condition code mode CC_V
to represent the overflow bit.
* config/arm/arm.c (maybe_get_arm_condition_code):
Add support for CC_Vmode.
(arm_gen_unlikely_cbranch): New function to generate common
rtl conditional branches for overflow patterns.

builtin overflow add operations.
(uaddv<mode>4, add<mode>3_compareC, addsi3_compareV_upper):
New patterns to support unsigned builtin add overflow operations.
(subv<mode>4, sub<mode>3_compare1): New patterns to support signed
builtin overflow subtract operations,
(usubv<mode>4): New patterns to support unsigned builtin subtract
overflow operations.
(negvsi3, negvdi3, negdi2_compare, negsi2_carryin_compare): New patterns
to support builtin overflow negate operations.
