Constant weld::CONF_SIR_OPT_KEY

pub const CONF_SIR_OPT_KEY: &str = "weld.optimization.sirOptimization";

Enables internal Sequential IR (SIR) optimizations.

This enables optimizations over the internal "sequential" Weld IR. Certain optimizations are easier to apply over this IR, and are thus implemented over the SIR rather than the expression tree.

This parameter should be set for compilation.
