devel/llvm18: Fix !CLANG plist

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

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*: LICENSE_DIR simplification

WRKSRC moved to the top of the source tree with llvm12.  As a result,
LICENSE_DIR became ${WRKSRC}/llvm.  Given that llvm11 the only port that
wasn't setting LICENSE_DIR, flip the script and default to
${WRKSRC}/llvm with llvm11 overriding.

ago.

devel/llvm[789]: restore arm_bf16.h to ARM backend

arm_bf16.h is generated for both armv7 and aarch64 so move it back to
ARM.  We don't support AArch64 without ARM so we can just move it and
not need to worry about duplicate supression (I'd previously fixed the
issue in llvm19 in a more complicated manner so this change removes the
duplicate supression and documents why it's not needed.)

devel/llvm18: fix host dependent compiler output for i386

Merge fixes for a couple cases where the compiler generated different
i386 code depending on the host.  In the base system this showed up as
very small differences in a couple object files in buildworld for i386
depending on the host architecture (i386 or amd64).

devel/llvm18: Backport __stack_chk_guard fix

Backport upstream commit commit 26464f2662d1 which marks __stack_chk_guard
dso_local except for PPC64 to fix loading an x86 kernel build with
--fstack-protector.

Also update to 18.1.8.  From a packaging perspective this only bumps the
version number since it only touchs libc++ which we don't ship.  As such,
I'd waited to bundle this bump with a functional change.

Drop releases.llvm.org, the LLVM project seems to nonlonger update it.

devel/llvm18: misc improvements

Fix worse runtime performance on Zen CPU when optimizing for Zen. [0]

Install all standard heaaders with clang.  Historically we've been
unable to build FreeBSD with the full set due to conflicts and/or
missing features between the compiler provided headers and
FreeBSD's headers.  I've verified that I can build world and kernel on
the main, stable/14, and stable/13 branches for amd64 so let's give it
another try in broader testing. [1]

devel/llvm18: PLIST_SUB improvements [NFC]

Chase changes in library suffixes and fix an overly pesimistic
substitution.  No functional change, but will reduce plist churn when 19
comes out assuming there aren't further upstream changes in suffixes.

devel/llvm18: 18.1.1 release

No functional change as all this release does does is set
LLVM_VERSION_SUFFIX="" (which we now do in the Makefile) and bump the
release version.

devel/llvm18: update to 18.1.0rc4

This is intended to be the last release candidate.

devel/llvm18: Update to 18.1.0rc3

Add a build conflict with ${ARCH}-binutils for COMPILER_RT to avoid
plist issues.  Technically this is only an issue for 64-bit
architectures that build 32-bit sanitizers (the presence of <triple>-ld
is picked up and it doesn't pass some cmake test), but it's easier to
just block all of them.

devel/llvm18: update to 18.1.0rc2

Add a libLLVM-18.so symlink to address hardcoding in Uses/llvm.mk and
other locations. [0]

devel/llvm18: fix plist issues with BE_NATIVE

Several flang modules depend on the PPC backend.

Add a couple more arm headers that depend on the Arm or AArch64
backends.

devel/llvm-devel: update to 18.1.0rc1

Update from 17 to 18 and connect to build.

Upstream has changed versioning so release branches bump the minor
version to 1 to differentiate them from the pre-branch development
version.

I've moved the .cmake files into STATIC_LIBS as they aren't useful
without .a files.  This removes from from the lite flavor (which will
likely be replaced with subpackages.) [0]
