Single Abstract Method support: synthesize SAMs
Under `-Xexperimental`, `typedFunction` invokes `synthesizeSAMFunction`
when the expected type for the function literal (`pt`) is not the built-in
`FunctionN` type of the expected arity, but `pt` does have a SAM
with the expected number of arguments.
PS: We'll require `import language.sam` instead of `-Xexperimental`,
as soon as the SIP is ready and there are more tests.
