Sanitizer spring cleaning

Sanitizer spring cleaning

  - Build ASAN and TSAN with skia_gpu=0.
  - Update tags to Ubuntu13.10-GCE-NoGPU for ASAN and TSAN bots.
  - Switch TSAN to Release mode.  It'll work better that way.
  - Remove Valgrind, ASAN, and TSAN builders.  They're runtime tools, so
    just building them won't tell us anything beyond a normal build,
    especially for Valgrind which doesn't build differently at all.

LGTM with one comment.

We could probably remove several more of the compile bots which are basically
duplicates of each other or aren't telling us anything. Let's save that for
another day.

We should perform a "special" master restart, in which we rename the history
directories for the renamed bots so that they retain their history.

File master/master_fyi_builders_cfg.py (right):

https://codereview.chromium.org/311233003/diff/1/master/master_fyi_builders_c...
master/master_fyi_builders_cfg.py:34: NO_GPU = repr({'skia_gpu': '0'})
I'd import this from master_builders_cfg rather than redefining it here.

Thanks Eric.  I'll follow up with a compile bot pruning.  You're right, many are
redundant, particularly among the Android builds.
