Maintaining an array of Expression-based sizes is not necessary as GLSL
only supports a single dimension, and doesn't allow any expression other
than a constant integer or nothing (meaning "unsized").

GLSL only allows one-dimensional arrays. This CL lowers SkSL's array
dimensionality limit from eight to one, and fixes all the tests that
this breaks. The rest of the code still technically supports
arbitrarily-deep array dimensionality; there are many opportunities for
code cleanup and simplification in followup CLs.

This CL fixes cases where array dimensions could be placed on the type
instead of the variable (`float[2] x` instead of `float x[2]`). It also
reports errors in cases where arrays aren't syntactically valid in
Metal, rather than emitting unusable Metal code. (Some of these cases
are actually invalid GLSL as well! But those fixes are coming in
followup CLs.)

Add more fields to SkCodec::FrameInfo, which describes the properties of
an individual frame in an animated image. This allows a client that
wishes to seek to determine frame dependencies so that they can decode
an arbitrary frame, which in turn will allow SkCodec to remove
SkCodec::FrameInfo::fRequiredFrame. Currently, SkCodec seeks through the
stream to determine frame dependencies, but this is unnecessary work
(and storage) for a client that does not want to seek.
These fields also support the proposed APIs in go/animated-ndk.
Move SkCodecAnimation::Blend from SkCodecAnimationPriv (and delete that
file) into SkCodecAnimation.h. Rename its values to be more clear.
Merge common code for populating SkCodec::FrameInfo.
Add a test for a GIF with offsets outside the range of the image. Note
that libwebp rejects such an image.

The proper approach for creating multi-dimensional array types is
complicated, so I added a function in SymbolTable which does it the
right way (addArrayDimensions). I found all the places in SkSL which
created arrays from base types and size arrays, and refactored them to
call addArrayDimensions instead of doing it manually.
I believe that this approach fixes a bunch of minor issues with multi-
dimensional array types; some are visible in the current codegen output,
and others are latent bugs. e.g. in some instances, a Variable's type()
was silently holding flipped array dimensions, but this never led to
a visible bug because we ended up using the VarDeclaration's baseType()
plus sizes() everywhere that the type was used. (In particular, this
caused debugging headaches in http://review.skia.org/340137 where I'd
use a Variable's type and suddenly its array dimensions would be wrong.)

My reference was mostly `man 3 sysctl`.
I'm pretty sure 'neon_fp16' is the right bit for FP16 NEON compute and
'neon_hpfp' just mean's its got f32<->f16 instructions, but I could be
mixed up. It'll become extremely obvious once I start using that bit.

The Metal return type from main() diverges from the SkSL source, so we
patch it in the Metal code generator. This CL improves the patching
process in multiple ways:
- A `return` statement from a fragment processor main() is rewritten to:
return *_out;
- A `return` statement from a vertex processor main() is rewritten to:
return (_out->sk_Position.y = -_out->sk_Position.y, *_out);
- We avoid emitting a duplicate `return *_out;` statement if we can
determine that main() already ends in a return statement. This is
harmless either way so it doesn't necessarily catch everything. (e.g.
it doesn't detect an if/else which returns at the end of both blocks.)
Also added a unit test which returns from the middle of a vertex shader,
since we didn't test this anywhere and we need to verify that
sk_Position.y will be negated. (This didn't work properly before.)

Previously, this would generate invalid code such as `[[user(locn-1)]]`.
We now generate a more-useful error at SkSL compilation time.

This was just wrong. It should be determine perspective
using the matrix that we are drawing with, and not the initial
matrix.

GLSL only supports arrays of samplers in very limited ways; they aren't
supported at all by SkSL. We now detect arrays of opaque objects and
reject the code.
We have several paths through the IR generator that create and process
array types; the unit test covers global and local variables, and array
on the type versus array on the variable.

Upcoming CLs are going to add more thread_locals to SkSL, so it makes
sense to bake this test into a convenient define.

Our stack contains values that are either F32 or I32, and notionally
stores them as F32, using pun_to_I32() when it's actually an int.
Instead, remove that F32 bias and store the skvm::Val, the type-erased
value ID that underlies both F32 and I32. Then reconstruct the types as
needed using pop_F32() / pop_I32(), or the now-smarter
unary/binary/ternary. Those helpers work in terms of Val now, and will
infer the right F32/I32 types from their argument functor. A few other
stack manipulators now also work in a type-agnostic way.
What do you think of this instead of separate F32/I32 stacks? The cond
and mask stacks are already conceptually crowding things a bit, and this
lets us keep the primary stack all in one place. And it'd be tricky to
index into split F32/I32 stacks for things like kLoad, kStore, kDup.

Take advantage of the integer properties that direct subrun
