re PR middle-end/15825 (if-cvt optimisation patch noce_try_sign_mask breaks apple-ppc-darwin port)
PR middle-end/15825
* ifcvt.c (unshare_ifcvt_sequence): Rename to end_ifcvt_sequence.
Use get_isns and end_sequence instead of accepting a seq argument.
Scan the instruction sequence for unrecognizable or jump insns.
(noce_try_move, noce_try_store_flag, noce_try_store_flag_constants,
noce_try_addcc, noce_try_store_flag_mask, noce_try_cmove,
noce_try_cmove_arith, noce_try_minmax, noce_try_abs,
noce_try_sign_mask): Use end_ifcvt_sequence to factor common code.
* gcc.dg/pr15825-1.c: New test case.
