Upgrade to LLVM 7.0.1 Release.

Avoid calling realpath unless it is actually needed (D17990).

Add all patches from base llvm/clang/lld/lldb 7.0 to devel/llvm70

This adds all the patches that were applied in the past to the
clang700-import branch, under contrib/llvm. After these, there only
minimal diffs left between the port sources and the base sources.

Most of these remaining diffs are due to #ifdef shortcuts in the base
sources, because we don't compile certain features in. Other diffs are
because the port has applied a few changes that we don't have in base.

Also switch to the common LICENSE defintion in devel/llvm-devel and
chase new USE_GNOME requirements (for libxml2).
