Fortran: improve expansion of constant array expressions within constructors
gcc/fortran/ChangeLog:
PR fortran/102787
* array.c (expand_constructor): When encountering a constant array
expression or array section within a constructor, simplify it to
enable better expansion.
gcc/testsuite/ChangeLog:
* gfortran.dg/array_constructor_54.f90: New test.
