syntax when name lookup finds multiple candidates. Overload resolution is then used to select the best candidate and map the overloaded member reference expression down to DotSyntaxCallExpr or DotSyntaxBaseIgnoredExpr, as appropriate. This implements part of <rdar://problem/11071641>, so that simple overload resolution works, but there is still a bit of cleanup to do. Swift SVN r1366
