[Bug fortran/20923] gfortran slow for large array constructors

With this simply modified case:

program sel
    implicit none
    integer,parameter              :: n=10
    integer                        :: i,j,k,l
    real,dimension(n*n*n*n) :: vect
    vect(:) = (/ ((((( (i+j+k+l+3)),i=1,n),j=1,n),k=1,n),l=1,n) /)
    print *, vect
end

Compilation time is reduced by 1/2 with the patch. Other more complex examples
need to be tested of course.
