[PATCH] Better distinguish OpenACC and OpenMP sections in libgomp.texi

[Julian Brown]

Hi,

This patch looks like it should have been attached to the following
email:

https://gcc.gnu.org/ml/gcc-patches/2018-09/msg01173.html

but it looks like the wrong patch (and ChangeLog!) were attached
instead. For convenience, I'll copy Cesar's blurb (mildly corrected)
from the previous message:

"This patch updates the libgomp documentation to more clearly identify
OpenMP-specific sections. Specifically, the sections "Runtime Library
Routine" and "Environment Variables" are now prefixed by OpenMP, because
those sections are not applicable to OpenACC."

I've re-checked that the generated libgomp.pdf looks ok.

OK? (Documentation, so should be OK for stage 4, IIUC.)

Thanks,

Julian
