Authentication-results: sourceware.org; auth=none

This patch by Than McIntosh to the Go frontend changes the backend
interface to pass the function to all the methods that create
statements.  Having the function available simplifies things if a
temporary variable has to be created during the construction of a
statement.

This also includes a change to the Mark_lvalue_varexprs helper class
to handle indirections on the left hand side of assignments (e.g.
"*x.y = ...").

Bootstrapped and ran Go testsuite on x86_64-pc-linux-gnu.  Committed
to mainline.
