[pushed] aarch64: Don't update EH info when folding [PR107209]

[Richard Biener via Gcc-patches]

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.

Thanks to Richard for the patch.  Tested on aarch64-linux-gnu & pushed.

        * 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.
