This patch fixes a bug introduced by refactoring. A cast from rtx_insn
to rtx_jump_insn in fix_crossing_conditional_branches was placed before
the check, and that caused ICE if the instruction is actually a call,
rather than a jump.

Bootstrapped/regtested on x86_64 linux and tested the regressed case
(PR34999) on aarch64 crosscompiler using the provided profiling data.

OK for trunk?
