Tagir Valeev ec8510b0a6 PsiPolyExpressionUtil#isBooleanOrNumericType: do not check bounds
JLS 15.25 says: ...has return type boolean or Boolean. or ...is convertible to a numeric type.
JLS 5.1.8 says:
A type is said to be convertible to a numeric type if it is a numeric type (§4.2), or it is a reference type that may be converted to a numeric type by unboxing conversion.

Nothing about bounds
PolyConditionalExpressionWithTargetPrimitive test behavior matches Java 9+ now (with --release=8)
