* basic-block.h (redirect_edge_and_branch_force,
redirect_edge_and_branch, block_label, forwarder_block_p): Declare.
* flow.c (redirect_edge_and_branch_force,
redirect_edge_and_branch, block_label, forwarder_block_p): Make global.
(redirect_edge_and_branch_force): Fix copying of lifeness information.
(block_label): Handle EXIT_BLOCK_PTR by returning NULL.
* ifcvt.c (dead_or_predictable): Take BB as an new destionation
instead of label; update CFG after transformation.
(find_if_case_1): Update call, use redirect_edge_and_branch_force
for finishing the transformation; handle even case where ELSE
does not follow THEN.
(find_if_case_2): Update call of dead_or_predictable; simplify
CFG update.
* emit-rtl.c (split_branch_probability): New global variable.
(try_split): Take care to set split_branch_probability and
create REG_BR_PROB note for new jump insns.
* md.texi (define_split): Document new feature.
* i386.c (ix86_split_fp_branch): Redistribute branch probability notes.
