/* From ECMA-335, I.8.7 Assignment compatibility:

|
The reduced type of a type T is the following:
|
||
|
|
|
||
|
|
1. If the underlying type of T is:
|
||
|
|
a. int8, or unsigned int8, then its reduced type is int8.
|
||
|
|
b. int16, or unsigned int16, then its reduced type is int16.
|
||
|
|
c. int32, or unsigned int32, then its reduced type is int32.
|
||
|
|
d. int64, or unsigned int64, then its reduced type is int64.
|
||
|
|
e. native int, or unsigned native int, then its reduced type is native int.
|
||
|
|
(NOTE: In NetFW/Mono (but not CoreCLR) implementations the reduced type is int32 or int64)
|
||
|
|
2. Otherwise, the reduced type is itself.
|
||
|
|
AND... enums are converted to their underlying type
