----- Type related -----
Return true if the conversion from INNER_TYPE to OUTER_TYPE is a
useless type conversion, otherwise return false.
This function implicitly defines the middle-end type system. With
the notion of 'a < b' meaning that useless_type_conversion_p (a, b)
holds and 'a > b' meaning that useless_type_conversion_p (b, a) holds,
the following invariants shall be fulfilled:
1) useless_type_conversion_p is transitive.
If a < b and b < c then a < c.
2) useless_type_conversion_p is not symmetric.
From a < b does not follow a > b.
3) Types define the available set of operations applicable to values.
A type conversion is useless if the operations for the target type
is a subset of the operations for the source type. For example
casts to void* are useless, casts from void* are not (void* can't
be dereferenced or offsetted, but copied, hence its set of operations
is a strict subset of that of all other data pointer types). Casts
to const T* are useless (can't be written to), casts from const T*
to T* are not.
