Richard Smith ff530305d1 Add prelude support for implicit conversion between integer literals and sized integer types. (#4525) 
In preparation for changing integer literals to be of `IntLiteral` type.
Conversions from the integer literal type are only permitted when the
value fits within the destination type.

For now, if conversion cannot be checked because the source value is a
symbolic constant, produce a symbolic constant representing the
conversion rather than rejecting it.
