(and a couple presubmit fixes)
This allows us to turn back on -Werror for LLVM coverage builds,
and more generally supports building with Clang 3.7.

This should be a drop-in replacement for most for-loops to make them run in parallel:
for (int i = 0; i < N; i++) { code... }
~~~>
sk_parallel_for(N, [&](int i) { code... });
This is just syntax sugar over SkTaskGroup to make this use case really easy to write.
There's no more overhead that we weren't already forced to add using an interface like batch(),
and no extra heap allocations.
I've replaced 3 uses of SkTaskGroup with sk_parallel_for:
1) My unit tests for SkOnce.
2) Cary's path fuzzer.
3) SkMultiPictureDraw.
Performance should be the same. Please compare left and right for readability. :)

Fix path bugs exposed by the path fuzzer.
Changes to existing gm and samplecode files defer their calls to construct
SkPath objects until the first draw instead of at test initialization.
Add an experimental call to SkPath to validate the internal SkPathRef.
Fix SkPath::addPoly to set the last moveto after adding a close verb.
Fix stroke to handle failures when computing the unit normal.
Add a unit test for the unit normal failure.
