Avoid conditional check for resource_collection_ in RenderWidgetHostViewAura::SendReturnedDelegatedResources.

The function RenderWidgetHostViewAura::SendReturnedDelegatedResources() is called only when
there is a valid resource_collection_ object. This seems a redundant check as the call site
already checks for it hence replacing the condition with a DCHECK(resource_collection_).

NaCl: Update revision in DEPS, r12687 -> r12694

This pulls in the following Native Client changes:

r12688: (jfb) Update TOOL_REVISIONS for PNaCl r12646->r12686
r12689: (jfb) PNaCl toolchain build: tell configure to ignore bindings.
r12690: (mseaborn) Enable testing nacl-gdb on ARM via gdb_tests
r12691: (dschuff) toolchain_build_pnacl: Build unsandboxed IRT for linux x86-32
r12692: (sbc) Add NACL_ABI_S_ISLNK() and others to stat.h
r12693: (sbc) Add missing isatty.c stub to nacl.scons and nacl.gyp
r12694: (kschimpf) PNaCl: Update LLVM revision in pnacl/COMPONENT_REVISIONS

Also, update locally-patch sys/signal.h in
native_client_sdk to match latest changes in newlib
(unfortunately its still needed until all the toolchains
contain the latest newlib headers).

Remove the native title bar (content_shell already has a blue custom
