397fdfdf18 Implement separate crop filter
Right now the crop image filter is hidden in src/ and is only used in
a new GM to test out its functionality. In later CLs the plan will be to
migrate individual filter effects away from the built-in crop rect to
composing themselves with this image filter.

Eventually, the crop filter will be made public as part of the
SkImageFilters factories so there can be independent control on input
and output cropping. Its features will also be expanded to support more
tile modes than just kDecal.

Once all other effects rely on this crop filter, the legacy system can
be deleted and the effects can be more easily updated to the rest of the
new image filter API. This crop filter is actually the first image
filter to be implemented only in terms of the new API (and skif coord
space types). This highlighted a few pain points that still exist in
terms of the API, where I have added comments to capture how they could
be improved. Unfortunately, they aren't addressable until the rest of
the implementations have been migrated.

cb40008b43 Implement switch in SkVM.
SkVM implements switches as a pseudo-loop; breaks are handled with the
condition mask just like a for loop. Fallthrough is handled via a
scratch Value in a temporary slot. `writeStore` neeeded to be refactored
to support writing into slot(s) without an associated Variable.

At IR generation time, SwitchStatements are now emitted without error
even in strict-ES2 mode. The GLSL code generator currently reports these
as an error in strict-ES2 mode, but this will be fixed in a followup
coming shortly (the switch will be rewritten as ifs inside a one-shot
loop, similar to our IR-rewrite strategy).

01754ecf12 Graphite: Rough out DrawCommandList and BoundsManager
Device will own and manage a BoundsManager, which it will use to decide
the sort and test Z's that it passes to the DrawCommandList in its
draw() implementations.

DrawCommandList might end up being owned by the SDC, with the SDC
exposing a similar drawing API. There will need to be some mechanism to
end a DrawCommandList and start a new one (the list moves into an
SDCTask). This would either happen from an external flush call, or in
the rare case where the representable Z values are exhausted and we
have to insert a depth buffer clear and start a new task that depends
on the prior one.

be056f4f62 Add switch statement support to PipelineStage.
This allows us to write SKSL_TEST_ES3 tests in SkSLTest and have them
run properly. Previously, such a test would assert inside the pipeline-
stage generator. In ES2 mode, we will rewrite switches as chained ifs,
but in ES3 mode we will want to continue emitting them as-is (they will
be faster than chained ifs on a modern GPU).

`writeSwitchStatement` is adapted from GLSLCodeGenerator.

eb68973c2f Disallow matrix ctors which overflow a column.
The GLSL spec allows matrix constructors containing vectors that would
split between multiple columns of the matrix. However, in practice, this
does not actually work well on a lot of GPUs!

- "cast not allowed", "internal error":
	Tegra 3
	Quadro P400
	GTX 660
	GTX 960
- Compiles, but generates wrong result:
	RadeonR9M470X
	RadeonHD7770

Since this isn't a pattern we expect to see in user code, we now report
it as an error at compile time. mat2(vec4) is treated as an exceptional
case and still allowed.

857c7f9dc5 Add program-too-large test using for loops without blocks.
The fuzzer has discovered a bug in our program size-checking logic; for
loops that immediately contain another for loop (with no block) were not
counting the inner loop's iterations. This allowed it to exceed our
maximum program-size threshold (and time out during SkVM compilation).

This test demonstrates the issue. A followup will fix it.

b701fa0ac0 Add non-square MatrixCompMult support to public SkSL in ES3 mode.
We already had a test case here, but it wasn't actually in operation.
The test has been split into ES2 (square) and ES3 (non-square) halves,
returns the color like a proper runtime effect, and it's now running in
dm.

Also, Metal doesn't natively support matrixCompMult, so it injects a
helper function; I tweaked the helper so it no longer requires an extra
result variable.

10c9f36bdd New approach to GrProcessor uniforms.
The important aspect is that it allows knowing the uniforms that will
be used by a set of processors without having to create ProgramImpls.

GrProcessor subclasses specify uniforms at creation time in a similar
style to how GrGeometryProcessors already specify attributes. That is,
they initialize a span of structs describing the uniform which may
contain void uniforms that are skipped. Unlike attributes, the struct
contains an offset into the processor where the data is stored.

GrUniformAggregator is used to collect the uniforms from all processors
that compose a draw and mangle their names. The ProgramImpl subclasses
query the aggregator for their uniform names when emitting code.

The old system for uniforms is left intact and only three processors,
one GP, one FP, and one XP, are updated to use the new system.

Some pieces that are missing before everything can be moved over:
-support for uniforms not owned by GrProcessor (e.g. rt-adjust)
-support for samplers
-helpers for common patterns
 (e.g. GrGeometryProcessor::ProgramImpl::setupUniformColor(),
  and the various matrix helpers on ProgramImpl)

7591d4b5ef Replace trio of XxxxLiteral types with a single Literal type.
Throughout SkSL we've begun using doubles as a convenient way to store
any SkSL value (int, float, bool) in a single type. This idea has now
been extended to literals. Rather than having three expression kinds for
integers, floats and boolean literals, we can have just one. These can
be accessed in a type-specific way (`floatValue`, `intValue`, and
`boolValue` return the expected type, or assert if it's not the
matching type), or in a type-agnostic way (`value` will return a double
and works on any type of Literal).

This allows us to remove a complex template trick (Literal<T> is gone),
removes two redundant Expression types, and and lets us reduce our code
size in ConstantFolder, FunctionCall, etc.

Most of the conversion process was pretty straightforward:
* `IntLiteral::Make` becomes `Literal::MakeInt`
* `x.is<IntLiteral>()` becomes `x.isIntLiteral()`
* `x.as<IntLiteral>.value()` becomes `x.as<Literal>.intValue()`
