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.

This extends the runStriped to all for return data.
GPU impl not done yet, will be done in a follow-on CL.

Slightly sharper, but far easier to hold:
- Remove Value union from interface, everything is a 32-bit
value type, or a collection thereof.
- Collapse to one version of Run (that takes count), and make
it a member on ByteCode.
- Similarly, move disassemble to ByteCodeFunction.

This converts the SkSL interpreter to operate in SIMT fashion. It handles
all the same features as the previous scalar implementation, but operates
on N lanes at a time. (Currently 8).
It's modeled after GPU and other parallel architectures, using execution
masks to handle control flow, including divergent control-flow.
