Basically the same deal as aarch64:
- a bunch of instructions to rewrite control
flow to be two loops, body and tail
- a bunch of instructions to support scalar
loads and stores in the tail
We can now remove the JIT::mask field.
I've removed the SkUNREACHABLE I'd put in for the ARM code... as
written the interpreter is still reachable by the loser if two threads
race to JIT the program. Medium term I plan to move JIT compilation to
a more proactive time, eliminating the need for the lock and letting the
interpreter become truly unreachable.
I had a little bit of a false start with what instructions to use for
scalar load8 and store8, first starting with instructions that loaded
via GP registers, then remembering vpinsrb and vpextrb can take a memory
argument, loading into xmm directly. I've left the first instructions I
used in the file, still implemented but only used from the unit tests.
They're pretty common and will probably be useful some day.

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.

Support forward references in Label.
In addition to tracking the current Label offset (used for
backward references essentially just the same as before this CL)
we also store a list of instructions that refer to each Label.
When a Label moves, each instruction gets a new displacement.
To make this a little easier, remove the 8-bit jump form on x86...
this way all x86 displacements are 32-bit and and all ARM 19-bit.
For now only cbz() supports this, just to start somewhere.
More to do but it's worth an early design review.

This adds a bunch of instructions we'll need to handle the N < 4 tail
within the JIT code on ARM.
- ldrb/strb are 1-byte load and stores
- sub subtracts without setting flags
- cmp just sets flags (actually just subs with an xzr destination)
- add b and b.lt, just like b.ne
- cbz and cbnz... we only need cbz but I accidentally did cbnz first
Once I add support for forward jumps, we'll be able to use these
instructions to restructure the loop to
entry:
hoisted setup
loop:
if N < 4, jump tail (cmp N,#4; b.lt tail)
... handle 4 values ...
jump loop (b loop)
tail:
if N == 0, jump end (cbz N, end)
... handle 1 value ...
jump tail (b tail)
end:

The primary purpose of this commit is to track upstream Wuffs more
closely.
A side effect is to pull in the Wuffs commit
5bea867f72
"Allow an LZW literal width of 1", which eliminates a difference between
the old third_party/gif decoder and the new third_party/wuffs decoder.
As the CodecTest.cpp comment says, the GIF spec explicitly says that the
LZW literal width should be at least 2, but in practice, GIF encoders
violate the spec. After that upstream commit, Wuffs has followed other
GIF decoders in being more liberal in what it accepts.
Codec_InvalidAnimated therefore no longer has a separate "#ifdef
SK_HAS_WUFFS_LIBRARY" section. The first frame of the test's GIF image
data, being the required frame of the third frame, no longer has an
invalid LZW literal width according to Wuffs.

Lays the infrastructure to use mixed samples internally, and begins
using nvpr with mixed samples on the default "gl" and "gles" configs.
In this rendition, we take the simplest approach possible re: stencil
attachments. We initially create a render target without stencil
(i.e., 0 samples). Then, any time a proxy needs a stencil buffer with
more samples than its target currently has, we create and attach a new
stencil buffer. However, we never "downgrade" a render target's
stencil attachment to one with fewer samples. So if the proxy only
needs one sample and the target has many, we leave it.
