This allows skslc to track the values of variables with constant
values across multiple statements and replace variable references with
constant values where appropriate.
The improved liveness tracking allows skslc to realize that a
variable is no longer alive if all references to it have been
replaced. It is not yet doing much with this information; better
dead code elimination is coming in a followup change.

This adds support for querying "sk_Caps.<cap>" directly from within an SkSL program.
Combined with the existing support for collapsing 'if' statements with constant tests,
this means we can query caps using ordinary 'if' statements and the tests will
collapse out at compile time.

-Wrange-loop-analysis triggers when we use a new-style for loop in a way that appears to unintentionally call a copy constructor on each non-trivial loop element instead of operating on them by reference.
