sys-devel/clang: Replace the non-upstreamable lib/clang patch

Replace the non-upstream patch allowing us to alter path for lib/clang
with the use of upstream CLANG_RESOURCE_DIR option (to fix file search
in driver code) combined with necessary symlinking (for tests) and moves
(for install) of installed headers.

-Subject: [PATCH 5/7] cmake: Supporting overriding runtime libdir via
- CLANG_LIBDIR_SUFFIX
-
-Make it possible to override the value of CLANG_LIBDIR_SUFFIX, and use
-it uniformly to control install location of runtimes (i.e. lib/clang),
-therefore supporting sharing a common runtime between multiple multilib
-variants.
-
-Previously, CLANG_LIBDIR_SUFFIX was pinned to LLVM_LIBDIR_SUFFIX
-and used only to define runtime path in driver code. This patch extends
-its use to building and installing the runtime (the former is needed for
-tests to work correctly).
-
-The goal is to support install layout alike "LLVM_LIBDIR_SUFFIX=64
-CLANG_LIBDIR_SUFFIX=''" -- where all shared libraries would be installed
-into ABI-specific /usr/lib64, while runtime (that is common between
-multilib ABIs) would be installed into /usr/lib.
-

-Patch: https://reviews.llvm.org/D23752
