[Patch, Fortran, F08] PR 45290: pointer initialization

[Janus Weil]

Hi all,

the attached patch fixes one remaining problem with F08 (non-NULL)
pointer initialization: The F08 standard forbids using pointers as
initialization target in pointer initialization statements, which we
failed to detect up to now. Implementation is straightforward, once
you know how to read the standard in this matter. The patch was
regtested on x86_64-unknown-linux-gnu. Ok for trunk?

Cheers,
Janus
