    i386: Fix ix86_option override after change [PR 113719]
    
    In ix86_override_options_after_change, calls to ix86_default_align
    and ix86_recompute_optlev_based_flags will cause mismatched target
    opt_set when doing cl_optimization_restore. Move them back to
    ix86_option_override_internal to solve the issue.
    
    gcc/ChangeLog:
    
            PR target/113719
            * config/i386/i386-options.cc (ix86_override_options_after_change):
            Remove call to ix86_default_align and
            ix86_recompute_optlev_based_flags.
            (ix86_option_override_internal): Call ix86_default_align and
            ix86_recompute_optlev_based_flags.
    
    (cherry picked from commit 499d00127d39ba894b0f7216d73660b380bdc325)
