re PR c++/59813 (tail-call elimination didn't fire for left-shift of char to cout)
PR c++/59813
PR tree-optimization/89060
* tree-ssa-live.h (live_vars_map): New typedef.
(compute_live_vars, live_vars_at_stmt, destroy_live_vars): Declare.
* tree-ssa-live.c: Include gimple-walk.h and cfganal.h.
(struct compute_live_vars_data): New type.
(compute_live_vars_visit, compute_live_vars_1, compute_live_vars,
live_vars_at_stmt, destroy_live_vars): New functions.
* tree-tailcall.c: Include tree-ssa-live.h.
(live_vars, live_vars_vec): New global variables.
(find_tail_calls): Perform variable life analysis before punting.
(tree_optimize_tail_calls_1): Clean up live_vars and live_vars_vec.
* tree-inline.h (struct copy_body_data): Add eh_landing_pad_dest
member.
* tree-inline.c (add_clobbers_to_eh_landing_pad): Remove BB argument.
Perform variable life analysis to select variables that really need
clobbers added.
(copy_edges_for_bb): Don't call add_clobbers_to_eh_landing_pad here,
instead set id->eh_landing_pad_dest and assert it is the same.
(copy_cfg_body): Call it here if id->eh_landing_pad_dest is non-NULL.
* gcc.dg/tree-ssa/pr89060.c: New test.
