Fortran: improve checking of array specifications
gcc/fortran/ChangeLog:
PR fortran/103505
* array.c (match_array_element_spec): Try to simplify array
element specifications to improve early checking.
* expr.c (gfc_try_simplify_expr): New. Try simplification of an
expression via gfc_simplify_expr. When an error occurs, roll
back.
* gfortran.h (gfc_try_simplify_expr): Declare it.
gcc/testsuite/ChangeLog:
PR fortran/103505
* gfortran.dg/pr103505.f90: New test.
