11a218444f Revert previous change: complexN only converts to complexN.
This was discussed with Ken and Russ.  6g has been changed,
and both compilers now work this way.  This avoids a double
type conversion--first to the float type, then to the complex
type.

c1045db1d8 go_spec: use PrimaryExpr as type switch expression
Without this change, the spec parses <-c.(type) as (<-c).(type)
but parses <-c.(int) as <-(c.(int)).

With this change, the former parses as <-(c.(type)).

All three parsers already implement this rule, because
they look for the "type" word during parsing of a standard
type assertion.  This change merely brings the
spec in line with the implementations.
