Subject: [PATCH, testsuite]: Fix gfortran.dg/coarray/event_3.f08 testcase (PR fortran/70696)

Hello!

As explained in PR70696, comment #17 [1], the referred testcase,
introduced as a testcase for PR70696, results in an uninitialized read
from x. Adding "save" attribute, as explained and required in the
comment #1, fixes the runtime failure for me.

    * gfortran.dg/coarray/event_3.f0: Add save attribute to x.

Patch was tested on x86_64-linux-gnu and alphaev68-linux-gnu, where it
fixes the runtime failure.

OK for mainline and release branches?

Uros.
