Allow function literal in string interpolation (dartbug.com/18137).

Allow function literal in string interpolation (dartbug.com/18137).

As of r34903, the VM allows function literals inside string
interpolation, even if the string is inside an initializer.  This
makes the corresponding change to the analyzer.

Not that it matters, but...

Because Dart allows using either double or single quotes, you can make source
code easier to read by using single quotes instead of escaped double quotes, as
in

   "class C { C() : a = '${(){}}'; }"
