Didier Spezia 70da2d0a2a cmd/compile/internal/gc: fix internal compiler error on invalid declaration
Following an empty import, a declaration involving a ? symbol
generates an internal compiler error when the name of the
symbol (in newname function).

package a
import""
var?

go.go:2: import path is empty
go.go:3: internal compiler error: newname nil

Make sure dclname is not called when the symbol is nil.
The error message is now:

go.go:2: import path is empty
go.go:3: invalid declaration
go.go:4: syntax error: unexpected EOF

This CL was initially meant to be applied to the old parser,
and has been updated to apply to the new parser.

Fixes #11610
