33d2055e59 GM: some header cleanup
gm.h includes sk_tool_utils.h but does not use it.

The bulk of this CL makes each gm that uses sk_tool_utils include it.

sk_tool_utils.h also provided SkRandom and SkTDArray,
so a couple GMs add those headers too.

eee3ced68f Disable tail calls inside Simple GM functions.
I haven't found any way to turn off the particular optimization (-foptimize-sibling-calls)
per-function, but I can control optimization settings coarsely:

   - on GCC, we can pick a particular -O level, so I've picked -O1 which does not
     enable -foptimize-sibling-calls
   - on Clang, we can only disable all optimization for a function
   - have no idea about MSVC

This should make sure the simple GM functions, e.g. all_bitmap_configs_GM(),
show up on stack traces when we crash.

2a24338c77 GM: replace boilerplate with macros
I have verified locally that nothing draws differently.

Motivation:
*   SK_SIMPLE_GM makes it easier to write a GM.
*   Reducing 1100 lines of code makes maintenance easier.
*   Simple GMs are easy to convert to Fiddles.

e4636aa173 Merge Replay and Quilt tasks, adding in all BBH implementations.
Replay isn't that helpful of a test any more now that we have the more
stringent Quilt tests.  Quilt was missing bounding box hierarchies, though,
while Replay was sort of testing RTree (pointlessly, as it was drawing without
any clip).  Now Quilt does everything, testing RTree, QuadTree, and TileGrid.

Quilt mode now falls back to drawing all at once (i.e. Replay) for GMs that
don't tile perfectly.  Still a TODO to make this check more flexible than exact
pixel matches.

Two GMs fail when using a BBH:
  - imageresizetiled
  - resizeimagefilter
We think we're not adjusting the bounds of save layers by their paint.
This is probably a bug, but one to be fixed separately from adding new tests.

91359bed48 Revert of Clean up Test's resourcePath code. (https://codereview.chromium.org/319473003/)
Reason for revert:
Some benchmarks are written in a way that makes this change unsafe (e.g. const char* resPath = GetResourcePath().c_str(); in SkipZeroesBench) and Valgrind and ASAN caught that.  We can try again after a more careful cleanup of GetResourcePath().

38aeb0fd7a DM: also run benches once.
Also:
  - make GrMemoryPoolBenches threadsafe
  - some tweaks to various DM code
  - rename GM::shortName() to getName() to match benches and tests

On my desktop, (289 GMs, 617 benches) x 4 configs, 227 tests takes 46s in Debug, 14s in Release.  (Still minutes faster than running tests && bench && gm.)  GPU singlethreading is definitely the limiting factor again; going to reexamine whether that's helpful to thread it again.

644629c1c7 Implement a benchmark for GrResourceCache
Adds "grresourcecache_add" and "grresourcecache_find" bench tests to test
GrResourceCache::add and GrResourceCache::find. The tests work only
with GPU backends, since GrResourceCache needs an GrGpu.

Modifies bench tests to override SkBenchmark::isSuitableFor(Backend)
function that specifies what kind of backend the test is inteded
for. This replaces the previous "fIsRendering" flag that would
indicate test that did no rendering.

Adds SkCanvas::getGrContext() call to get the GrContext that the
canvas ends up drawing to. The member function solves a common
use-case that is also used in the benchmark added here.

62b50b7bb8 Have GMs read the GrContext via a setter/getter rather than a global.
GetGr's current global state makes things rather tricky to run GPU GMs in
parallel (DM).  This API change will let me feed the right GrContext to the
right GM in DM.

I'm not planning on changing the status quo in GM-the-tool: the new getters and
setters still just return the same global.

bd6343b1d6 Rewrite SkTRegistry to take any trivially-copyable type.
Obviously these are all currently function pointers of type T(*)(P) for various
T and P.  In bench refactoring, I'm trying to register a function pointer of
type T(*)(), which can't be done as is (passing P=void doesn't work).  This
also lets us register things like primitives, which is conceivable useful.

805df1aa1d Fixes for factory GM.
Skip cross process pipe playback in gm/factory.cpp. Add a new flag to
gm.h to skip only this form of pipe playback.

In gmmain.cpp, use a bitmap encoder function for serialization that
stores the encoded data if present, and use a bitmap decoder on
deserialization. This allows gm/factory to work through serialization.
Also respect the new pipe skipping flag.

2bbc2c945b Add an option to create unpremultiplied bitmaps.
Currently they cannot be used directly by Skia, but
the pixels can be used elsewhere.

SkImageDecoder:
Add functions to require unpremultiplied output
and query the presence of the requirement

SkImageDecoder_libpng:
SkImageDecoder_libwebp:
SkImageDecoder_WIC:
Respect the requirement for unpremultiplied output.
TODO: Fix SkImageDecoder_CG.

SkScaledBitmapSampler:
Add procs to skip premultiplication and a boolean
parameter to use those procs.

ImageDecodingTest:
Test unpremultiplied bitmap decoding.

SampleUnpremul:
Add a sample which allows visually comparing between the
unpremultiplied version (copied into a premultiplied bitmap,
since drawing unpremultiplied is not currently supported)
and a premultiplied version of image files.

gm.h:
Add a getter for the resource path, so Samples can use it.

As of patch set 13, https://codereview.chromium.org/16816016/
and https://codereview.chromium.org/16983004/, which were
approved separately.
