Update Makefiles under lib/clang and usr.bin/clang for 11.0.0 builds,
and also bump the version in the mtree files.

Adjust libllvmminimal and tblgen Makefiles so all the tblgen executables
build.

Move all sources from the llvm project into contrib/llvm-project.

This uses the new layout of the upstream repository, which was recently
migrated to GitHub, and converted into a "monorepo". That is, most of
the earlier separate sub-projects with their own branches and tags were
consolidated into one top-level directory, and are now branched and
tagged together.

Updating the vendor area to match this layout is next.

Update libllvmminimal and llvm-tblgen Makefiles, so llvm-tblgen and
clang-tblgen can build.

Make llvm-tblgen and clang-tblgen build.

Update clang, lld and llvm version numbers for r321414, and update build
glue.

executable build.

Initial update of clang/llvm build glue, for building just a minimal
clang executable.

Initial updates to llvm/clang build glue.

Completely revamp the way llvm, clang and lldb are built.

* Bootstrap llvm-tblgen and clang-tblgen with a minimal llvm static
library, that has no other dependencies.
* Roll up all separate llvm libraries into one big static libllvm.
* Similar for all separate clang and lldb static libraries.
* For all these libraries, generate their .inc files only once.
* Link all llvm tools (including extra) against the big libllvm.
* Link clang and clang-format against the big libllvm and libclang.
* Link lldb against the big libllvm, libclang and liblldb.

N.B.: This is work in progress, some details may still be missing.

It also heavily depends on bsd.*.mk's support for SRCS and DPSRCS with
relative pathnames, which apparently does not always work as expected.
For building llvm, clang and lldb though, it seems to work just fine.

The main idea behind this restructuring is maintainability and build
peformance. The previous large number of very small libraries, each
with their own generated files and dependencies was slow to traverse
and hard to understand.

Possible future improvements:
* Only build certain targets, e.g. for most regular users having just
one target will be fine. This will shave off some build time.
* Building the big llvm, clang and lldb libraries as shared (private)
libraries.
* Adding other components from the LLVM project, such as lld.
