* fortran/options.c (gfc_init_options): Initialize
flag_argument_noalias to 3.
* doc/invoke.texi: Document new flag -fargument-noalias-anything.
* tree-ssa-alias.c (may_alias_p): If flag_argument_noalias > 2,
argument pointers may not alias any other storage.
* common.opt: Define option -fargument-noalias-anything.
* tree-ssa-structalias.c (intra_create_variable_infos): Fortran
alias semantics is specified by flag_argument_noalias > 2.
