0b2d2290fe powerpc: Enable LLDB on all powerpc architectures
While LLDB on powerpc and powerpcspe builds as-is, on powerpc64 and
powerpc64le it requires adding a couple of additional source files
to build.

adc88b9c01 Build libclang also if LLDB is enabled
LLDB depends on libclang as it uses Clang as the expression parser.
Previously setting WITHOUT_CLANG but leaving LLDB enabled (as default)
resulted in a build failure.

Users who set WITHOUT_CLANG in order to reduce build time or size
might want to set WITHOUT_LLDB in addition to WITHOUT_CLANG, or use
WITHOUT_TOOLCHAIN instead.

021385aba5 Add WITH_LLVM_BINUTILS to install LLVM binutils instead of Elftoolchain
When WITH_LLVM_BINUTILS is set, we will install the LLVM binutils as
ar/ranlib/nm/objcopy/etc. instead of the elftoolchain ones.
Having the LLVM binutils instead of the elftoolchain ones allows us to use
features such as LTO that depend on binutils that understand LLVM IR.
Another benefit will be an improved user-experience when compiling with
AddressSanitizer, since ASAN does not symbolize backtraces correctly if
addr2line is elftoolchain addr2line instead of llvm-symbolizer.
See https://lists.freebsd.org/archives/freebsd-toolchain/2021-July/000062.html
for more details.

This is currently off by default but will be turned on by default at some
point in the near future.

c1f7d8dd23 clang: Build with -fno-strict-aliasing when using GCC
Somewhat ironically, there are strict aliasing violations in Clang,
which can result in the following assertion failure:

  Assertion `*(NamedDecl **)&Data == ND && "PointerUnion mangles the NamedDecl pointer!"' failed.

Upstream's clang/CMakeLists.txt specifically (not LLVM as a whole)
passes -fno-strict-aliasing if the compiler is not Clang, and this fixes
the above issue.

This was seen when cross-building from Linux using a bootstrap
compiler, but likely also affects worlds built with a new enough
external GCC toolchain.

48397f6c7d libllvmminimal: Add missing Support/ABIBreak.cpp
When building natively on RISC-V, linking the bootstrap clang-tblgen
fails with:

  ld: error: undefined symbol: llvm::EnableABIBreakingChecks
  >>> referenced by PrettyStackTrace.cpp
  >>>               PrettyStackTrace.o:(.sdata+0x0) in archive

  /usr/obj/usr/src/freebsd-src/riscv.riscv64/tmp/obj-tools/lib/clang/libllvmminimal/libllvmminimal.a

This is likely due to Error.h's inclusion of abi-breaking.h. It's
unclear why this only affects RISC-V, but perhaps relates to its more
eager use of .sdata due to the ABI's support for linker relaxations.
Regardless, this is theoretically an issue for all architectures.

fe815331bb build: provide a default WARNS for all in-tree builds
The current default is provided in various Makefile.inc in some top-level
directories and covers a good portion of the tree, but doesn't cover parts
of the build a little deeper (e.g. libcasper).

Provide a default in src.sys.mk and set WARNS to it in bsd.sys.mk if that
variable is defined. This lets us relatively cleanly provide a default WARNS
no matter where you're building in the src tree without breaking things
outside of the tree.

Crunchgen has been updated as a bootstrap tool to work on this change
because it needs r365605 at a minimum to succeed. The cleanup necessary to
successfully walk over this change on WITHOUT_CLEAN builds has been added.

There is a supplemental project to this to list all of the warnings that are
encountered when the environment has WARNS=6 NO_WERROR=yes:
https://warns.kevans.dev -- this project will hopefully eventually go away
in favor of CI doing a much better job than it.

147d7b567f llvm: add a build knob for enabling assertions
For head/, this will remain eternally default-on to maintain the status quo.
For stable/ branches, it should be flipped to default-off to maintain the
status quo.

There's value in being able to flip it one way or the other easily on head
or stable branches, whether you want to gain some performance back on head/
(for machines there's little chance you'll actually hit an assertion) or
potentially diagnose a problem with the version of llvm on an older branch.

Currently, stable branches get the CFLAGS+= -ndebug line uncommented; going
forward, they will instead have the default of LLVM_ASSERTIONS flipped.
