PNaCl: Update LLVM revision in pnacl/DEPS

This pulls in the following LLVM changes:

0abed14: (jfb@chromium.org) Revert "PNaCl ABI checker: Disallow ExtractValue and InsertValue instructions"

This should force a rebuild of the LLVM toolchain, but without the
ExtractValue check that broke 255.vortex. I'll it pull in to
TOOL_REVISIONS tomorrow.

BUG=none
TEST=PNaCl toolchain trybots
