    PR fortran/93340 - fix missed substring simplifications

    Substrings were not reduced early enough for use in initializations,
    such as DATA statements.  Add an early simplification for substrings
    with constant starting and ending points.

    gcc/fortran/ChangeLog:

            * gfortran.h (gfc_resolve_substring): Add prototype.
            * primary.c (match_string_constant): Simplify substrings with
            constant starting and ending points.
            * resolve.c: Rename resolve_substring to gfc_resolve_substring.
            (gfc_resolve_ref): Use renamed function gfc_resolve_substring.

    gcc/testsuite/ChangeLog:

            * substr_10.f90: New test.
            * substr_9.f90: New test.
