Subject: [PATCH] pgo: fix PGO builds with clang
MIME-Version: 1.0
Content-Type: text/plain; charset=UTF-8
Content-Transfer-Encoding: 8bit

Add stubs for shm_chain_new(), shm_chain_free() and shm_unref(). This
fixes ‘pgo’ linking failures in the ‘generate’ phase when doing a PGO
build with clang.

Closes #642
