devel/llvm-cheriot: New LLVM 21 based snapshot

devel/llvm-cheriot: new snapshot

devel/llvm-cheriot: New LLVM 20.1.3 based snapshot

devel/llvm-cheriot: break up with devel/llvm-cheri

There isn't enough commonality between llvm-cheri and llvm-cheriot due
to increasing version skew so give llvm-cheriot it's own Makefile.

No functional change intended.  Port version bumped due to WWW change.
Update to the latest version to follow immediately.

devel/llvm-cheriot: add missing depend on py-myst-parser

devel/llvm-{cheri*,morello}: new snapshots

Update llvm-cheri to a new LLVM 17 based snapshot, llvm-cheriot to an
LLVM 18 based snapshot, and llvm-morello to a snapshot with new function
pointer semantics to better support compartmentalization.

Update the wrapper script to enable the new function pointer semantics
on sufficently new CheriBSD system.

devel/llvm-cheriot: Fix !CLANG plist

llvm-debuginfo-analyzer isn't part of Clang, but was matched by the
overly broad pattern `-analyzer`.

devel/llvm-cheriot: fix plist for EXTRAAS

This should have been updated as part of the commit below and the
PORTREVISION bump did apply to all. I was working on two things related
to these ports (one of which didn't touch llvm-cheriot) and got mixed
up.

devel/llvm*: flip LICENSE_FILE_BSD3CLAUSE setting [NFC]

The location of this license file moved in LLVM 16.  Since I'm doing
cleanup in this area and the split of ports is about 50/50, switch to
setting the old location in the older ports so the newer ports set fewer
variables.

devel/llvm-cheriot: new LLVM 17 based snapshot

The CHERIoT LLVM baseline has been updated to LLVM 17.

devel/llvm-{cheri,cheriot,morello}: update

Update to the latest snapshots.

We've done OK so far with installing standard headers as part of
devel/llvm## ports so extend that to these ports.  This is certainly
correct for llvm-cheriot.  Practical testing is likely required for the
others.

devel/llvm-{cheri,cheriot,morello}: link llvm-cxx{dump,filt}

These commands were some how not linked into bin long ago.  Correct
this error.

(Some other commands are also missing, but were specifically missing
llvm-cxxfilt).

devel/llvm-{cheri,cheriot,morello}: assorted fixups

Allow override of GH_PROJECT and GH_ACCOUNT[0] and fix GH_PROJECT in
llvm-cheriot.  No change in the source, but the filename is now
corrected.

Centralize include of Makefile.snapshot.

devel/llvm-{cheri,cheriot,morello}: XTOOLCHAIN option

Make the cross toolchain file optional and disable it completely for
cheriot where the compiler targets an architecture we'll ever support
(RV32E).

devel/llvm-{cheri,cheriot,morello}: new snapshots

Major changes:
    llvm-cheri: merge LLVM 15
    llvm-cheriot: switch the fork at github.com/CHERIoT-Platform
    llvm-morello: merge LLVM 14

Rework patching and filtering of commands and man pages to better
accomdate version skew between the different ports now that all three
have different bases.

Centralize the addition of ${.CURDIR}/files to EXTRA_PATCHS.

devel/llvm-cheriot: compiler for CHERIoT ISA

Add a port of the CHERIoT compiler.  The CHERIoT ISA adds CHERI to
RV32e (a microcontroller RISC-V variant).  A number of products based
on CHERIoT are in the pipeline including the Sonata board from lowRISC's
Sunburst Project (https://www.sunburst-project.org).
