Tried to comment my logic, but it's totally possible that we run on some
device where this doesn't work. From a strict reading of the relevant
specs, what I'm doing shouldn't work on the Nexus 5X, but it's necessary
to get correct results.

To build shaderc, gyp used to punt to cmake, which did not work well on the bots and I couldn't find any way to pipe the variables into cmake which would have made it happy.
So, I wrote a gyp file for shaderc and its dependencies. Nothing super complicated (thank goodness), except for the files that spirv-tools needed generated.

The custom font manager does not implement all onCreateFromStream
overloads leading to warnings. Since this needs to be implemented
anyway, implement it now.

On my Mac (so, immintrin), this improves compile time, both wall and cpu,
by about 16%. To test I ran this on an SSD with files hot in their caches:
$ env CC=/usr/bin/clang CXX=/usr/bin/clang++ ./gyp_skia && \
ninja -C out/Release -t clean && \
time ninja -C out/Release
Before: 159 wall / 3367 cpu
159 wall / 3368 cpu
After: 137 wall / 2860 cpu
136 wall / 2863 cpu
I also tried further refining immintrin down to emmintrin / tmmintrin / smmintrin etc.
That made no signficant difference, so I've kept immintrin for its simplicity.

This fixes serialize-8888 for 2 GMs on Mac that I'm now unblacklisting.
I think another was already fixed, and two more were Windows-only.
Seems safe to use encoded_size=1 as another sentinel here (like we already
use =0); I can't imagine any encoded image format that can encode an image
in a single byte.
I suspect this is the root of the referenced bug too,
but this is a good idea even if not.

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.

SkMipMap only deals with the levels it generates.
That is to day, it deals with mipmap levels 1-x, not 0-x.
Other functions reflect thing when indexing.
They go from 0 to x-1 (giving the index into SkMipMap's contents).
ComputeLevelSize should also follow that same indexing.

Instead of two synchronization systems (in_signal_handler, gMutex),
we can just use one. This simplifies the signal handler logic to:
- first thread through grabs the lock, prints what's running and a stack trace,
then exits
- all other threads just sit waiting on that lock until exit kills them
Previously I think all threads were racing to exit, which can kill the process
before the printing thread is done. That truncated the output, which is dumb.
Plus...
refactor slightly so that crash_handler() shows up at the top of the stack
trace rather than some odd name for a lambda inside setup_crash_handler().

Because we recognize commonly used gamma tables and
parameters as 2.2f, about 98% of jpegs with color profiles
will pass through this xform (assuming the dst is also
2.2f). Sample size is 10,322 jpegs.
I won't go crazy with performance numbers because this is
a work in progress, particularly in terms of correctness.

(300x280, most common form of sRGB profile)
Decode Time + QCMS Xform 1.28 ms
QCMS Xform Only 0.495 ms
Decode Time + Skia Opt Xform 1.01 ms
Skia Opt Xform Only 0.235 ms
Decode Time + Xform Speed-up 1.27x
Xform Only Speed-up 2.11x
FWIW, Skia xform time before these optimizations was
41.1 ms. But we expected that code to be slow.

Currently this is not actually hooked into the system.
To give some context, in a follow up CL I'll add this to GrDrawTarget.
For this I will move the gpu onDraw command to the GpuCommandBuffer as well.
For GL this will end up just being a pass through to a non virtual draw(...)
on GrGLGpu, and for vulkan it will mostly do what it currently does but
adding commands to the secondary command buffer instead.
