src.conf: Add WITH_LLVM_LINK_STATIC_LIBRARIES build knob

In commit 2e47f35be5dc libllvm, libclang and liblldb were converted into
private shared libraries. This allowed clang, lld, lldb, and other llvm
tools to be linked against these shared libraries, which makes them
smaller and avoids duplication.

However, this also comes at the cost of some performance, since the
dynamic libraries are quite large, and contain lots of long symbols
(mangled C++ identifiers).

Add a WITH_LLVM_LINK_STATIC_LIBRARIES build knob that can be used to go
back to the previous behavior: libllvm, libclang and liblldb are built
as internal static libraries, i.e. only available during buildworld, and
fully linked into the various executables such as clang, lld, etc.

Convert libllvm, libclang and liblldb into private shared libraries

This allows clang, lld, lldb, and other llvm tools to be linked against
these shared libraries, which makes them smaller and avoids duplication.

Since these are not quite the same as the shared libraries shipped by
the upstream llvm build system, and we do not want to expose the ABI to
external programs such as ports, make them private libraries.

Note that during the cross-tools stage they are still built as static
libraries, so the cross compiler and linker are static binaries, as they
have always been.

This also requires a depend-cleanup.sh kludge which will be added in a
follow-up commit, to ensure binaries are rebuilt against the shared
libraries in case of incremental builds.

Optionally create full debuginfo for llvm-related executables

Commit de6feefdb7cfd 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 ab80f0b21fbb9c44d40e6f7a99090188f4ed2f71. 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.

Rework {clang,lldb,llvm}-tblgen invocations to add --write-if-changed

This flag ensures that the tblgen tools do not actually touch the

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.

Ensure .inc files are regenerated when llvm/clang tblgen binaries change

When doing a fully incremental build (with WITHOUT_CLEAN enabled), from
a commit before llvm 15 was merged (3264f6b88fce), 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.)
