GrTextureAccess optionally includes an instance, computed from the src
and dst color spaces. In all common cases (no color space for either src
or dst, or same color space for both), no object is allocated.
This change is orthogonal to my attempts to get color space attached to
render targets - regardless of how we choose to do that, this will give
us the source color space at all points where we are connecting src to
dst.
There are many dangling injection points where I've been inserting
nullptr, but I have a record of all of them. Additionally, there are now
three places (the most common simple paths for bitmap/image rendering)
where things are plumbed enough that I expect to have access to the dst
color space (all marked with XFORMTODO).
In addition to getting the dst color space, I need to inject shader code
and uniform uploading for appendTextureLookup and friends.

On some platforms, a newly-created buffer was liable to be CPU backed.
This would break code that expected a VBO (aka instanced rendering).
This change adds an optional flag to GrResourceProvider that requires
a buffer to be created in GPU memory.
It also moves the CPU backing logic into Gr land in order to properly
cache real VBOs on platforms that prefer client-side buffers.

Adds a module that performs instanced rendering and starts using it
for a select subset of draws on Mac GL platforms. The instance
processor can currently handle rects, ovals, round rects, and double
round rects. It can generalize shapes as round rects in order to
improve batching. The instance processor also employs new drawing
algorithms, irrespective of instanced rendering, that improve GPU-side
performance (e.g. sample mask, different triangle layouts, etc.).
This change only scratches the surface of instanced rendering. The
majority of draws still only have one instance. Future work may
include:
* Passing coord transforms through the texel buffer.
* Sending FP uniforms through instanced vertex attribs.
* Using instanced rendering for more draws (stencil writes,
drawAtlas, etc.).
* Adding more shapes to the instance processor’s repertoire.
* Batching draws that have mismatched scissors (analyzing draw
bounds, inserting clip planes, etc.).
* Bindless textures.
* Uber shaders.

__mulodi4() is roughly,
int64_t __mulodi4(int64_t a, int64_t b, int* overflow) {
int64_t result = a*b;
*overflow = did_overflow(result);
return result;
}
It's used by Clang's __builtin_smulll_overflow(), which is basically the same
except it swaps the positions of the return value and the out parameter.
DNG SDK in turn uses __builtin_smulll_overflow().
When building ARMv7 binaries with Clang, __mulodi4() turns up as a missing symbol.
That's because it's defined in a separate compiler-rt library. I have not been
able to link that. Instead, I've provided our own trivial __builtin_smulll_overflow().
Before this patch both nanobench and DM failed dynamically linking __mulodi4(). After this patch nanobench runs for a while, eventually segfaulting. DM immediately segfaults.

For this I will move the gpu onDraw command to the GpuCommandBuffer as well.
For GL this will end up just being a pass through to a non virtual draw(...)

adding commands to the secondary command buffer instead.

When targetting iOS and using gyp to generate the build files, it is not
possible to select files to build depending on the architecture. Due to
that, the skia code was disabling all optimisation when SK_BUILD_FOR_IOS
was defined.
Since it is possible to select the correct optimised version when using
gn, this pessimisation is hurting the build. Introduce a new define to
disable the optimisation SK_BUILD_NO_OPTS. It will be used by Chromium
when building skia for iOS with gyp but not gn.
Define SK_BUILD_NO_OPTS along-side SK_BUILD_FOR_IOS for all files that
look like build configuration (Xcode projects, gyp configuration files,
public.bzl) in order to avoid introducing breakage on those builds.

- remove dead code
- rewrite float -> int converters
The strategy for the new converters is:
- convert input to double
- floor/ceil/round in double space
- pin that double to [SK_MinS32, SK_MaxS32]
- truncate that double to int32_t
This simpler strategy does not work:
- floor/ceil/round in float space
- pin that float to [SK_MinS32, SK_MaxS32]
- truncate that float to int32_t
SK_MinS32 and SK_MaxS32 are not representable as floats:
they round to the nearest float, ±2^31, which makes the
pin insufficient for floats near SK_MinS32 (-2^31+1) or
SK_MaxS32 (+2^31-1).
float only has 24 bits of precision, and we need 31.
double can represent all integers up to 50-something bits.
An alternative is to pin in float to ±2147483520, the last
exactly representable float before SK_MaxS32 (127 too small).
Our tests test that we round as floor(x+0.5), which can
return different numbers than round(x) for negative x.
So this CL explicitly uses floor(x+0.5).
I've updated the tests with ±inf and ±NaN, and tried to
make them a little clearer, especially using SK_MinS32
instead of -SK_MaxS32.
I have not timed anything here. I have never seen any of these
methods in a profile.

Implemented as a different subclass for SkColorShader (which is also private) partly to make the CL clearer/simpler, and partly for flatten/unflatten compatibility. Later I'm sure we could combine these if that proves useful.
Lots of TODOs at the moment, but still valuable to get reviewed.
Note: this ignores the question (for the moment) about how to interpret SkColor in the larger world. That needs to happen, but this CL is more focused on what *else* to do besides handle the old-style input (and old-style pipeline).
