Roll Clang 233105-2:238013-1

Note to sheriffs: we're expecting a ~400 kB size regression due to
a bug fix that causes more loop unrolling in this Clang version.

hans@chromium.org changed reviewers:
+ thakis@chromium.org

[hans, 2015-05-22 19:58:23]

This is like https://codereview.chromium.org/1144933003, but also includes
r237984 which fixes the blink miscompile from the previous roll attempt, and
r237972 which fixes an ARM miscompile.

tbr'ing brettw because the gn change is the same as previously reviewed

Apparently this one got fixed in 238011

I think 238013 looks good.

Only one red tryjob:
linux_chromium_chromeos_asan_rel_ng: Looks like a timeout. It failed on a
whitespace CL too:
