clang bots: Use gcc 4.8.5 instead of 4.8.2 as stage1 compiler.

clang bots: Use gcc 4.8.5 instead of 4.8.2 as stage1 compiler.

For reasons not fully understood, some of clang's tests started failing
when building clang with gcc 4.8.2 but they pass with 4.8.4 or 4.8.5.
Since we do bootstrap builds when building clang binaries, the stage1
host compiler doesn't matter much to us, so just flip the bots to
gcc 4.8.5 and move on with life.

I built 4.8.5 (in a precise vm) with:

  contrib/download_prerequisites
  mkdir build && cd build
  ../configure --prefix=$HOME/gcc485precise --enable-languages=c,c++ --enable-checking=release
  time make -j10
  make install-strip
  tar czf gcc485precise.tgz gcc485precise
  cd ~
  ~/gsutil/gsutil cp -n -a public-read gcc485precise.tgz gs://chromium-browser-clang/tools/gcc485precise.tgz

i.e. I switched from `make install` to `make install-strip`, which also reduces
download size from 125MB to 30 MB.
