Upgrade our copies of clang, llvm, lld, lldb, compiler-rt and libc++ to
the upstream release_70 branch r348686 (effectively, 7.0.1 rc3). The
release will follow very soon, but no more functional changes are
expected.

Do not install GNU ld if lld is /usr/bin/ld

GNU binutils ld.bfd 2.17.50 does not support ifuncs and produces broken
binaries when ifuncs are in use. When LLD_IS_LD is default we have an
ifunc-capable system linker and can just avoid installing ld.bfd.

Move llvm-profdata build into MK_LLVM_COV block

llvm-profdata is used with llvm-cov for code coverage (although llvm-cov
can also operate independently in a gcov-compatible mode).
Although llvm-profdata can be used independently of llvm-cov it makes
sense to group these under one option.

Also handle these in OptionalObsoleteFiles.inc while here.

libbe(3)/bectl(8): Make consistent with beadm

vermaden (maintainer of beadm) points out the following inconsistencies:
- "missing command" is not printed prior to usage if the error is simply a
missing command; this should be obvious from the context
- "bectl rename" isn't using the "don't unmount" flag (zfs rename -u), so
the active BE can't be renamed. It doesn't make sense in our context to
*not* use -u, so use it.

Documentation updates reflect the above and note an inconsistency with the
'destroy' command that is consistent with other parts of the base system.

A fix for libbe(3) not properly being installed to /lib is included.
SHLIBDIR should have been added when it was moved in r337995.

This file ends up being 2MB in size. For small systems this is a waste
of space but its a tradeoff.
