Out of bounds access with constant indices is a compile error.
At runtime, causes the interpreter to fail. Made several other
conditions trigger the same failure logic, and updated all
uses of the interpreter to validate success.

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.
