[PATCH 0/2] OpenMP parallel region scope tests

[Kevin Buettner]

This two part patch set adds tests which attempt to access variables at
various scopes from within several different types of OpenMP parallel
regions.

Patch 1/2 adds some OpenMP support procs to lib/gdb.exp.
Patch 2/2 contains the actual tests.

There are more than a few tests which should work, but don't.  They have
been either xfailed or kfailed.  I used kfail to mark problems within
gdb.  I used xfail to mark problems in the compiler or in libgomp. 
(Perhaps I should have used kfail for those problems as well?)

I have patches (which have not been posted yet) which fix all of the
kfailed tests.
