Commit de6feefdb7 limited the amount of debuginfo generated for clang
and other llvm-related executables. This was done to save disk space and
memory during building, but it makes debugging any of these executables
much harder.
Add a new src.conf(5) setting, WITH_LLVM_FULL_DEBUGINFO, to generate
full debuginfo instead. This is off by default, but could for example be
enabled for release builds or snapshots, so llvm executables are easier
to debug.

This reverts commit 470f9f13de.
I need more time to figure out how to make this work correctly with
incremental builds, which it currently miserably fails on.
There is no reason anymore to not build these as PIE. Unfortunately
bsd.lib.mk does not allow for building _only_ PIE static libraries, so
lib/clang/Makefile.inc needs a kludge to work around that issue.

This is another part of fixing the WITH_ASAN build. Some additional
source files had to be added to libllvm and liblldb, since the ASan
instrumentation causes symbols in those files to be referenced.

Headers from src/include were in the runtime-dev package but
subdirectories of src/include ended up in utilities-dev by default.
Neither package is a good choice - the headers in src/include are not
useful without the libraries contained in clibs-dev.
This moves the standard C headers to clibs-dev (C++ headers are already
in this package). While working on this, I found that various clang
libraries and headers were also bundled into utilities-dev by default
so these are also moved to clang-dev.
I also added a FreeBSD-build-essential meta package to make it simple to
install all the toolchain parts.

The FreeBSD driver support for clang tested explicitly for 32-bit
Intel, MIPS, or PowerPC targets where /usr/lib32/libcrt1.o was
present to decide whether -m32 should use /usr/lib32. At jrtc27's
suggestion, simply test for a 32-bit platform rather than adding
arm to the list. Upstreamed as

Bump the freebsd version to force a bootstrap build. This is one
step in adding support for -m32 on arm64.

This reverts commit ab80f0b21f. The intent
of this change was to avoid possible compilation errors when certain
.inc files were not regenerated, but the method turns out to cause way
more rebuilds than anticipated. Another method will have to be found,
and in the mean time, WITH_CLEAN is the solution that always works.
Fixes: ab80f0b21f
This flag ensures that the tblgen tools do not actually touch the
produced .inc file, if there are no changes to the contents. In turn,
this may prevent a number of rebuilds of files that include such .inc
files, saving build time.
While here, ensure that the shell invocations to locate the used tblgen
binary do not show unnecessary error messages.

When doing a fully incremental build (with WITHOUT_CLEAN enabled), from
a commit before llvm 15 was merged (3264f6b88f), to a commit after
that, a number of .inc files were not regenerated. This could lead to
unexpected compilation errors when these .inc files were included from
llvm-project sources, similar to:
In file included from /usr/src/contrib/llvm-project/clang/lib/CodeGen/CGBuiltin.cpp:8268:
/usr/obj/usr/src/amd64.amd64/lib/clang/libclang/clang/Basic/arm_mve_builtin_cg.inc:279:18: error: no matching constructor for initialization of 'clang::CodeGen::Address'
Address Val2 = Address(Val1, CharUnits::fromQuantity(2));
^ ~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~
Work around this by making the .inc files dependent on the tblgen binary
used for generating them. E.g., we can relatively safely assume that if
the binary gets updated, the .inc files must also be updated. (Although
this is not 100% optimal, the gain by complicating things even more is
probaby not worth the effort.)

The MACHINE_ABI and TARGET_ABI variables are used to set the middle of
the target triple (e.g., "-unknown-" or "-gnueabihf-"). They are not set
by any tool in the base system and I've only found the latter mentioned
in one review online. As such, rename them to to MACHINE_TRIPLE_ABI and
TARGET_TRIPLE_ABI to clear the way to use MACHINE_ABI as a supplement to
MACHINE_CPU, etc.
