Group sequence of LETT definitions into LET/LET* expressions where
appropriate.
* interp/g-opt.boot (jumpToToplevel?): New.
(singleAssignment?): Likewise.
(groupVariableDefinitions): Likewise. Use them.
(optimizeFunctionDef): Group toplevel variable definitions into
a bind expression.
* interp/g-util.boot (expandBind): Tidy.
* interp/c-util.boot (transformToBackendCode): Refrain from
enclosing let-expressions in SEQ if not needed.
