Description

Summary of changes

Adds an Instruction::simplify method to see if an instruction should be simplified by being replaced with a known value. The method does not recurse* so it cannot simplify cases like 2 * x / 2.

  • It actually does recurse in one case: it checks for !!x to simplify it to x. This might be moved to wherever we check for the more complex simplifications down the line, or perhaps we'll add those simplifications in the same place as well.
