nacl-clang: use gas by default instead of the LLVM assembler

Update COMPONENT_REVISIONS to bring in the following LLVM changes:
  e2a83b3 (dschuff@chromium.org): Remove nacltlsaddr32 from assembly layer
  74eb265 (dschuff@chromium.org): Use "." instead of label difference for GOT address calculations with gas

and the following clang change:
  0de7964 (dschuff@chromium.org): Use gas (non-integrated assembler) by default for nacl-clang

Also remove the SCons hack that disabled the integrated assembler when
building .S files
