[patch, fortran] Fix PR 62106

[Thomas Koenig]

Hello world,

the attached patch fixes the regression by making sure we never
try to create a temporary variable from a temporary variable,
which happened in the wrong order.

Regression-tested.  OK for trunk and 4.9?

        * gfortran.h (symbol_attribute):  Add fe_temp flag.
        * frontend-passes.c (is_fe_temp):  New function.
        (create_var):  Don't add a temporary for an already
        created variable or for a constant.
        (combine_ARRAY_constructor):  Remove special handling
        for constants.
