[PATCH, gfortran] Add data attribute to vars in old-style initializations

Subject: [PATCH, gfortran] Add data attribute to vars in old-style initializations

:ADDPATCH gfortran:

Hi,

While working on PR 20441 (-finit-local-zero), I came across this bug: variables with old-style initializations don't get tagged with the data attribute. This means that we allow some illegal code (see attached testcase), and it makes it difficult to figure out which variables are uninitialized.

Bootstrapped and regression tested on i686-pc-linux. Okay for trunk and 4.1?
