Orkuncakilkaya 0998cb5a18 feat(compiler): a slice index is checked against its length 
A slice has carried { ptr, len, cap } since it existed and nothing ever read
the len: every index emitted a bare getelementptr. Running off the end of one
wrote into whatever the allocator had put next, and the program died somewhere
else entirely - a maroon-lake crash took a day to find because the stack named
a texture upload and the write was in a telemetry buffer five frames earlier.

Now each index loads the length and compares unsigned, which rejects a negative
index in the same instruction, and a failure aborts with the location the other
located errors use:

    oob.ludic:9: index out of range: 7, len 3

`words` and the other raw buffers are unchanged - they are a bare malloc with no
length to check, which is the argument for moving off them.

The SPIR-V variants are regenerated in the same commit: shaders --check was
failing against the edited GLSL.
