[PATCH, testsuite]: Remove statements with to effect from two fortran testcases

[Uros Bizjak]

Hello!

Attached patch removes two statements with no effect. These two
statements operate with uninitalized variables, and - depending on the
uninitialized value - can cause denormal FP exceptions when compiled
with -O0. The exception causes runtime failure on the target that
requires -mieee for full IEEE support, e.g. alpha.

The patch removes these statements.

    * gfortran.dg/dec_parameter_1.f (sub1): Remove statement with no effect.
    * gfortran.dg/dec_parameter_2.f90 (sub1): Ditto.

Tested on alphaev68-linux-gnu.

OK for mainline and backports?

Uros.
