This patch to the Go frontend by Cherry Zhang removes
stack_allocation_expression from the backend interface. Now that we
consistently use temporary variables for temporaries,
stack_allocation_expression is no longer used. Bootstrapped and ran
Go testsuite on x86_64-pc-linux-gnu. Committed to mainline.
