1. builtin "int_expect", which makes the evaluator work on more integer operations such as left/right shift (with traps) and integer conversions. 2. builtin "_assertConfiguration", which enables the evaluator to work with debug stdlib. 3. builtin "ptrtoint", which enables the evaluator to track StaticString 4. _assertionFailure API, which enables the evaluator to report stdlib assertion failures encountered during constant evaluation. Also, enable attaching auxiliary data with the enum "UnknownReason" and use it to improve diagnostics for UnknownSymbolicValues, which represent failures during constant evaluation.

Add support to the constant evaluator for:
builtin "int_expect", which makes the evaluator work on more integer operations such as left/right shift (with traps) and integer conversions.
builtin "_assertConfiguration", which enables the evaluator to work with debug stdlib.
builtin "ptrtoint", which enables the evaluator to track StaticString
_assertionFailure API, which enables the evaluator to report stdlib assertion failures encountered during constant evaluation.
Also, enable attaching auxiliary data with the enum "UnknownReason" and use it to improve diagnostics for UnknownSymbolicValues, which represent failures during constant evaluation.
