2020-12-31 devel/llvm60: Uses Python 2.7 which is EOLed upstream, no more
consumers left

Revert r559792 to unbreak INDEX and bulk -a
It seems a lot of reverse dependencies were missed

With hat:	portmgr

Remove most expired ports that depend on Python 2.7:

Exceptions are:
- mail/mailman, our listservers still use it
- www/chromium, solely because of popular demand,
  upstream is (slowly) working on porting it to Python 3
- ports that have actual patches for Python 3 against
  them (Cinnamon and a few unrelated other ports)
- llvm70 and qt5-webengine because they seem to have a lot
  of dependencies which need further analysis
- sysutils/uefi-edk2-bhyve because bhyve seems to use them
- python2 and python27 themselves

I'm sure there will be complaints, but the nice thing about
a version control system is that we can revert and adjust things.

devel/llvm*: Avoid extraneous escapes

All of these single quotes are safe on their own, as they're enclosed in
double quotes. Removes the escapes, because they're currently passed through
to the underlying regex engine as \' to be interpreted as '.

A future change will forbid this escape, then an even further future change
will actually imbue \' with special meaning based on GNU interpretation
("end of subject").

No PORTREVISION bump or rebuild is needed, as they're functionally
equivalent.

Reorder Makefiles a bit to group similar things together.

Remove support for generating patch files from upstream SVN revisions.
The required interfaces have been disabled for some time and LLVM is in

No functional changes (pkg-plist changes are simply ordering).

Don't override the compiler on armv7.

The base system compiler is now sufficent to build and link.

No version bump.  While technically required for armv7, forcing everyone
to rebuild for this minor change that doesn't effect actual use is not
justifiable.

Add all patches from base llvm/clang/lld/lldb 6.0 to devel/llvm60

This adds all the patches that were applied in the past to head, under
contrib/llvm.  After these, there only minimal diffs left between the
port sources and the base sources.

Most of these remaining diffs are due to #ifdef shortcuts in the base
sources, because we don't compile certain features in.  Other diffs are
because the port has applied a few changes that we don't have in base.

While here, use Makefile.LICENSE from the devel/llvm-devel port.
