compiler: Traverse types of call expressions.
https://gcc.gnu.org/PR67968 provides a test case that causes a gccgo
crash on valid code. The compiler failed to build the hash and equality
functions required for a type descriptor. The descriptor is for an
unnamed type that is being returned by a function imported from a
different package. The unnamed type is being implicitly converted to an
interface type by a return statement. The fix is to ensure that the
type of a call expression is always traversed.
Test case sent out for the master testsuite as
https://golang.org/cl/16532 .
