[Patch, fortran] PR20863 and PR20082 - things PURE and impure

[Paul Thomas]

:ADDPATCH fortran:

These might be said to be legacy PRs:)  Seriously, though, getting the 
constraints right for PURE procedures is important and it is a shame 
that these have lain around for so long.

The patch remedies two omissions in applying the constraints associated 
with variables in PURE procedures.  The testcase lifts the reporters' 
originals and exercises the fix a bit more.  The patch and the Changelog 
pretty much speak for themselves.

Bootstrapped and regtested on x86_ia64/FC5 - OK for trunk and 4.2?
