The current recipe in Type_guard_expression for creating a Bexpression
performs a type conversion at the Type level, but doesn't invoke
Backend::convert_expression to capture the conversion for the back
end. This patch by Than McIntosh adds code to create a BE type
conversion operation. Bootstrapped and ran Go testsuite on
x86_64-pc-linux-gnu. Committed to mainline.
