07cc6440dc go_spec: don't allow parens around the literal type of composite literals 
Background: The current spec is imprecise with respect to the parsing ambiguity
for composite literals: It says that the ambiguity arises when the TypeName form
of the LiteralType is used. The following code:

    if (B) {} ...

is not using the TypeName form (but the parenthesized TypeName form) and thus
could be interpreted as:

    if ((B){}) ...

instead of

    if B {} ...

Both compilers and gofmt choose the latter interpretation. One could fix the
spec by making the clause regarding the parsing ambiguity more precise ("...using
the _possibly parenthesized_ TypeName form of the LiteralType..."). The alternative
(chosen here) is to simply disallow parenthesized literal types. Except for a single
test case (test/parentype.go) there appears to be no Go code under $GOROOT containing
parenthesized literal types. Furthermore, parentheses are never needed around a
literal type for correct parsing.

- consolidated rules about assignment compatibility in

- be consistent with specyfing that nil is the value
  for uninitialized variables that can be nil (this
  was not specified clearly for pointers, functions, interfaces)
- added/fixed various related links throughout

1d282a8eb2 go spec: Base comparison compatibility on assignment compatibility. 
Specifically:
- Simplified definition of comparison compatibility and folded into
  section on comparison operators since it's only used there.

This is a small language change/cleanup. As a consequence:
- An interface value may now be compared against a non-interface value.
- Channels with opposite directions cannot be compared directly anymore
  (per discussion with rsc).

11a218444f Revert previous change: complexN only converts to complexN.

type.
