aarch64: Don't update EH info when folding [PR107209]
The AArch64 folders tried to update EH info on the fly, bypassing
the folder's attempts to remove dead EH edges later. This triggered
an ICE when folding a potentially-trapping call to a constant.

PR target/107209
* config/aarch64/aarch64.cc (aarch64_gimple_fold_builtin): Don't
update EH info on the fly.
gcc/testsuite/
* gcc.target/aarch64/pr107209.c: New test.
