1) Replace a couple commas with semicolons.
2) Make sure to zero a couple vectors.
1) has no effect on code generation.
2) does add a bunch of self-vxorps, but they're cheap and we already do
the equivalent for <AVX SSE code, and they're in not very
performance-critical routines. We could circle back and guard these
with !defined(JUMPER_IS_OFFLINE) if we really need the vectors to start
uninitialized for speed.

The baseline compiled into Skia is now pretty much identical.
Minor diffs due to the offline code using -ffp-contract=fast, and the
baseline not. Explicit calls to fma() are still FMAs, but we're no
longer letting the compiler uncover FMAs we didn't explicitly call out.
If this goes well, we should be able to turn on the 8-bit pipeline.

This was created by looking at warnings produced by clang's
-Wzero-as-null-pointer-constant. This updates most issues in
Skia code. However, there are places where GL and Vulkan want
pointer values which are explicitly 0, external headers which
use NULL directly, and possibly more uses in un-compiled
sources (for other platforms).

Whether JUMPER is defined is starting to get a little overloaded:
- are we compiling offline (defined) or as part of Skia (!defined)?
- are we using Clang vector extensions (defined) or scalars (!defined)?
This splits JUMPER into these two separate concerns:
- JUMPER_IS_OFFLINE
- JUMPER_IS_SCALAR, JUMPER_IS_NEON, JUMPER_IS_AVX2, etc.
The upshot is that we'll now use Clang vector extensions when available
for our "portable" baseline. On x86-64 and ARMv8 compiled by Clang,
we're guaranteed to pick up SSE2 and NEON respectively. Our -Fast
bot should even get all the way to AVX2.
Another CL will do some refactoring in SkJumper to remove the redundant
copies of guaranteed vector code on x86-64 and ARMv8. I didn't want to
do that here yet to demonstrate that there is zero effect on the .S
files from this CL.

The tiny path added to PathTest.cpp has
tinier cross products (e.g. 1e-12)
so appears to be a series of unbending
lines as far as getConvexity is concerned.
This point fix looks for paths that
do not bend left or right or go backwards,
but do have a bounds, and calls them
concave.
A better fix may be to consider empty
and degenerate paths to be concave
instead of convex; I don't know if
anyone relies on the existing behavior.
Another better fix may be to change
the math to compute the path turns
even though the numbers are very small;
on the surface, very difficult.

The most interesting parts of this are how plus interacts with partial
coverage. Plus needs its clamp to happen after the lerp.
Luckily, some of its math folds away:
d' = clamp[ d*(1-c) + (s+d)*c ] ==
clamp[ d - dc + sc + dc ] ==
clamp[ d + sc ]
What's nice there is that coverage can be folded into the src term.
This suggests that we can re-write the plus stage to clamp internally
(and thus, be viable for 8-bit) if we always pre-scale with coverage.
We don't have a way to pre-scale with 565 coverage until now, but
it's only a step or two away from there. We can use the alternate
formulation we derived for alpha for lerp_565, calculating the alpha
coverage from red, green, and blue coverages _and_ the values of src
and dst alpha.
While we already pre-scale srcover today for 8-bit or constant coverage,
we cannot do the same for 565. When evaluating the expression
d' = s + (1-a)d
we need the a term to be pre-scaled with red's coverage when calculating
dr', with blue's when calculating db', etc. Essentially we need to
carry around a bunch of extra values, and we've got no way to do that.
So instead, we'll just carefully pre-scale plus with any coverage, and
keep post-lerping srcover when we have 565 coverage.
