Performance improvements in invoke-polymorphic runtime support
Fineses the runtime support for invoke-polymorphic to improve
MethodHandle benchmark measurements by an average of 14%.
- Faster conversion checks for non-exact invokes.
- Avoid conversion checks for CallerTransformers and Transforms.
- Fast path for exact invokes avoiding conversion checks.
- Use cheaper constructs where possible.
Most of these changes are driven by simulation in callgrind.
