[Bug lto/41756] LTO: -flto -O1 linking files compiled with -fno-exceptions with ones compiled with exceptions yields error "BB 14 can not throw but has an EH edge"

I wonder if we should simply ignore -fno-exceptions/-fexceptions passed to
lto1 and rely on the automated discovery.

The testcase btw works for me on i?86.

The proposed patch would delete handling of OPT_fexceptions from
register_user_option_p and add flag_exceptions = 0 to lto_init_options
in case you can still reproduce the issue.
