Predicate exprMaxVal

Gets the maximum value that this expression could represent, based on its type.

For example, if expr has a signed 32-bit type then the result is 2^31 - 1.

Note: Due to the way casts are represented, rather than calling exprMaxVal(expr) you will normally want to call exprMaxVal(expr.getFullyConverted()).
