Hideto Ueno f2b9dc4758 [Attributor] ValueSimplify Abstract Attribute 
Summary:
This patch introduces initial `AAValueSimplify` which simplifies a value in a context.

example
- (for function returned) If all the return values are the same and constant, then we can replace callsite returned with the constant.
- If an internal function takes the same value(constant) as an argument in the callsite, then we can replace the argument with that constant.
