This time, with manual program memory management instead of std::vector<void*>.
Using STL types from SkOpts_hsw.cpp is not safe. Things like std::vector<void*>
are inlined but not anonymous, so they're deduped by the linker arbitrarily. This
is bad when we pick the version compiled with AVX instructions on a machine that
doesn't support AVX...
std::vector<Stage> was safe before because Stage itself was anonymous. While not anonymous, std::vector<Stage> is unique to the compilation unit, because you can only refer to the anonymous Stage in the compilation unit.

Textures that we sample on the GPU are always premul, so we should

Colors that are xformed on the CPU are always unpremul, so clamping to
[0,1] is correct. Add a comment explaining that.

It's turned out to be surprisingly subtle to make the optimization colorspace
correct (it's not today, but with this CL the affected images become colorspace
correct).
Before implementing a colorspace correct color shader, let's check we really need this.
Update: I should say, it's hard to do this optimization and make the resulting color shader be both colorspace correct and "legacy correct". SkColorShader and SkColor4fShader are both colorspace correct. It's just challenging to create one shader that's correct for both modes from an image.

Label AA edges as three types: inner, outer, and connector. This

the top or bottom vertex has been merged with a vertex on edges
of different types.
Changed the "collinear edges" sample from the concavepaths GM for a
"fast-foward" shape, which more clearly shows the problem being fixed
here. (The collinearity from the "collinear edges" was actually being
removed earlier up the stack, causing the path to become convex and
not exercise the concave path renderers anyway.)

minor pixel diffs in a number of other tests.

If a frame does not have a valid transparent index and it covers the
prior frame, it does not really depend on that frame. Instead, it
depends on the frame that the prior frame depends on.
Determine this once we have parsed the local color map (if any), so a
transparent index out of range of the color map is not considered
valid.
Share code that determines whether a frame has a transparent pixel.
Add a test that we compute the dependencies correctly. randPixelsAnim.gif
has 13 frames. After the first, the frames cover all combinations of
- Whether the prior frame was keep, restoreBG or restoreToPrevious
- Whether the new frame covers the prior frame
- Whether the new frame has a transparent pixel
(It only does so when using a global color table. It may make sense to
expand the test to also cover using local color tables.)
The test caught a bug where we incorrectly reused an existing
SkColorTable for a different frame. Fix that bug by keeping track of
the transparent index associated with the current SkColorTable.

The overhead of a stage today is 3 x86 instructions, typically looking something like this:
- movq (%rdi), %rax // Load the next stage function pointer.
- addq $0x10, %rdi // Step our progress ahead 16 bytes to that next stage.
- jmpq *%rax // Transfer control to that stage.
But if we make sure the pointer's in esi/rsi, we can use lodsd/lodsq to do those first two steps in one instruction:
- lodsq (%rsi), %rax (≈ movq (%rdi), %rax; addq $0x8, %rsi).
- jmpq *%rax
This CL rearranges things so that we can take advantage of this and generally trim off an instruction of overhead. Instead of a vector of {Fn, ctx} pairs, we'll flatten it down into a single interlaced program vector of void*, basically just ommitting any null context pointers. We pass the pointer to program as the second argument to Fn, putting it in rsi. These two changes together make getting the next Fn to call or the current context the same cheap lodsq instruction, encapsulated as load_and_increment().
Here's how the simple "modulate" blend stage changes:
vmulps %ymm4, %ymm0, %ymm0
vmulps %ymm5, %ymm1, %ymm1
vmulps %ymm6, %ymm2, %ymm2
vmulps %ymm7, %ymm3, %ymm3
movq (%rdi), %rax
addq $0x10, %rdi
jmpq *%rax
~~~~~~~~>
vmulps %ymm4, %ymm0, %ymm0
vmulps %ymm5, %ymm1, %ymm1
vmulps %ymm6, %ymm2, %ymm2
vmulps %ymm7, %ymm3, %ymm3
lodsq (%rsi), %rax
jmpq *%rax
This does make getting the current context a one-time, destructive operation. It's switched from referring to ctx as a void* directly to using ctx() as a thunk that returns a void*. No stage so far has ever referred to ctx twice, and it all appears to inline, so this seems harmless. "matrix_2x3" is a good example of what stages that use context pointers end up looking like:
lodsq (%rsi), %rax
vbroadcastss (%rax), %ymm9
vbroadcastss 0x8(%rax), %ymm10
vbroadcastss 0x10(%rax), %ymm8
vfmadd231ps %ymm10, %ymm1, %ymm8
vfmadd231ps %ymm9, %ymm0, %ymm8
vbroadcastss 0x4(%rax), %ymm10
vbroadcastss 0xc(%rax), %ymm11
vbroadcastss 0x14(%rax), %ymm9
vfmadd231ps %ymm11, %ymm1, %ymm9
vfmadd231ps %ymm10, %ymm0, %ymm9
lodsq (%rsi), %rax
vmovaps %ymm8, %ymm0
vmovaps %ymm9, %ymm1
jmpq *%rax
We can't do this with MSVC, as there's no intrinsic for it I can find, and they disallow inline assembly, and rsi is not used to pass arguments to functions there anyway. ARM doesn't need it... it does this in two instructions naturally anyway. We could do this for 32-bit x86 but I'd just rather focus on x86-64.
It's unclear to me that this makes things any faster, but doesn't appear to make things any slower, and makes I think both the code and disassembly simpler.
