Remove WWW entries moved into port Makefiles

Commit b7f05445c00f has added WWW entries to port Makefiles based on
WWW: lines in pkg-descr files.

This commit removes the WWW: lines of moved-over URLs from these
pkg-descr files.

Add WWW entries to port Makefiles

It has been common practice to have one or more URLs at the end of the
ports' pkg-descr files, one per line and prefixed with "WWW:". These
URLs should point at a project website or other relevant resources.

Access to these URLs required processing of the pkg-descr files, and
they have often become stale over time. If more than one such URL was
present in a pkg-descr file, only the first one was tarnsfered into
the port INDEX, but for many ports only the last line did contain the
port specific URL to further information.

There have been several proposals to make a project URL available as
a macro in the ports' Makefiles, over time.

Changelog: https://github.com/jrprice/Oclgrind/releases/tag/v21.10

Update LLVM dependency to LLVM12 - minimum LLVM11 is required upstream.

devel/oclgrind: fix build on powerpc64 elfv2

LLVM 8 works by default in elfv1 mode, which doesn't really work on FreeBSD with
our gcc 4.2, but supports switching to elfv2. Since it build properly on elfv2,
hardcode it until the port switches to newer LLVM.

devel/oclgrind: update to tip of repository

Most notably fixes a bunch of memory leaks.

Bump PORTREVISION for ports depending on the canonical version of GCC
as defined in Mk/bsd.default-versions.mk which has moved from GCC 8.3
to GCC 9.1 under most circumstances now after revision 507371.

This includes ports
 - with USE_GCC=yes or USE_GCC=any,
 - with USES=fortran,
 - using Mk/bsd.octave.mk which in turn features USES=fortran, and
 - with USES=compiler specifying openmp, nestedfct, c11, c++0x, c++11-lang,
   c++11-lib, c++14-lang, c++17-lang, or gcc-c++11-lib
plus, everything INDEX-11 shows with a dependency on lang/gcc9 now.

This includes ports

Fix port builds for architectures which remain on gcc as the default compiler.
This will primarily help powerpc64.

For archs where clang is the default compiler, these changes will have no
effect, as the base compiler already has these capabilities (primarily, but
not exclusively, c++-11).

Tested for no-harm on amd64.

While here, pet portlint.
