Previously the pixel data passed to the client was only valid during
the client's callback. This meant if the client wanted to defer
processing of the data a copy was necessary.
Now we pass an object to the callback and the pixel lifetime is tied
to the lifetime of that object.
The object may be holding a GPU transfer buffer mapped. We don't assume
that the object will be released on the direct GrContext thread. So
when the object is destroyed it posts a message to a new type,
GrClientMappedBufferManager, hanging off the direct context. The direct
context will periodically check for messages and unmap and then unref
buffers so that they can be reused. Currently this is done in
GrContext::performDeferredCleanup() and GrDrawingManager::flush().
The old API is kept around for backwards compatibility but it is
reimplemented as a bridge on top of the new mechanism.
Also a utility function to SkImageInfo is added to directly make a new
info with a specified dimensions rather than passing the width and
height separately to makeWH().

- Update the parameter lists to both run and runStriped so
that they're in the same (sane) order, named consistently,

- Add the same count-based safety checks to run that were
already in runStriped.
- Remove the N parameter to run, it was only used to run
things one-at-a-time (other than one spot in unit tests),
and it simplifies the code quite a bit. If you want to run
multiple times, use the striped version. I also moved that
functions 'N' earlier in the parameter list, to make the
pattern of the remaining parameters clearer.
- Remove an interpreter benchmark class that was never used.

move us to just checking format renderability (without GrCT) in classes

2x faster than calling drawVertices as the impl.
Lots more to do in future CLs
- much of the time is spent in malloc, as we cons-up private shaders.
we *could* create a private shader and wack its data for each draw
(breaking the immutable contract, but that may be ok for a raster-only
internal-use shader...)
- also spend time building the pipeline for each draw, even though
all that has changed is a color payload (and the ctm). A custome
stage(s) that exposed its private data could be reused with new
data...

These didn't work correctly, and they're extremely tricky to get right
in the vectorized execution model (vs. structured control flow). As a
side effect, determine the maximum stack depth used for the execution
masking - the same idea will be used for the primary stack in a later
CL. Add a unit test to verify the new restriction, and fix two places
that were relying on this feature before.
In addition, boolean external values need to be masks. I may implement
this in the code-gen at some point, but this is already a fringe
feature, so just fix the one unit test for now.

There are a few places that have been checking whether the *proxy*
needs stencil, in order to determine if the current render target
context needs stencil. This is problematic since a render target
context can not require stencil itself, but wrap an existing proxy
that already has stencil.

From now on, sample counts always refer to the number of actual color
samples, and render targets don't have separate color and stencil
sample counts.
If mixed samples support is available when making a
"GrAAType::kCoverage" draw, then an op may attach and use a mixed
sampled stencil buffer internally. But this will all be invisible to
the client.
After this CL, we temporarily won't have a mode to use nvpr with mixed
samples. That will soon be fixed by a follow-on CL that enables nvpr
with mixed samples in the normal "gl" and "gles" configs.

This new bench lets us measure the overhead of program building,
optimization, and JITting. Surprisingly, at head the optimization in
Builder::done() takes longer than the JIT.
The new bench clocks in around 40µs on my laptop at head,
then 32µs after switching val_to_reg to be an std::vector,
then 27µs after switching deaths to be an std::vector too,
then 22µs after switching fIndex to be an SkTHashMap,
then 20µs after calling program.reserve(fProgram.size()),
then 19µs after switching JIT data maps to SkTHashMap too.
I tried swapping some std::vector for SkTDArray to no benefit, actually
a little detriment. So I think this is roughly all the low-hanging
fruit, with time split now roughly equally between Builder::Done(),
JITting in Program::eval(), and the original calls to Builder
themselves.
Also disable perf dumps on Mac. No real value there until I can dump a
dylib, and it's just one more thing I have to remember to disable before
running this sort of benchmark.

This moves the responsibility for allocating executable code out of
Assembler. The pages Xbyak uses are obviously executable, so this is
redundant right now, but it'll let us switch to something simple like
std::vector<uint8_t> as we continue to cut out Xbyak.
Make how Program holds its cached JIT program slightly less of a mess.

Made up a threshold between linear and slope searching.
For a count of 100 here are the before and after timings.
The first two lines are being changed. The latter 2 are

Try: out/release/nanobench --match _charToGlyph
Pseudo plan to use this:
- attach to whatever typeface backends need it (probably just freetype)
- have a purge/limiting scheme (e.g. only cache N entries)
- if we care, make the search fancier (e.g. binary, slope, etc.)
