re PR target/58864 (ICE in connect_traces, at dwarf2cfi.c:NNNN)
PR target/58864
* dojump.c (save_pending_stack_adjust, restore_pending_stack_adjust):
New functions.
* expr.h (struct saved_pending_stack_adjust): New type.
(save_pending_stack_adjust, restore_pending_stack_adjust): New
prototypes.
* optabs.c (emit_conditional_move): Call save_pending_stack_adjust
and get_last_insn before do_pending_stack_adjust, call
restore_pending_stack_adjust after delete_insns_since.
* expr.c (expand_expr_real_2): Don't call do_pending_stack_adjust
before calling emit_conditional_move.
* expmed.c (expand_sdiv_pow2): Likewise.
* calls.c (expand_call): Use {save,restore}_pending_stack_adjust.
* g++.dg/opt/pr58864.C: New test.
