    Fix "overwrite of unused"

commit 9b10738bb3cd5ddda976363fde44983b0ac38a12
Author: Marek Marecki <address@hidden>

    Add basic SA for blocks
    
    This is able to analyse "enter" and "leave" instructions. Entered blocks
    share their register usage profile with their surrounding frame (and
    this is implemented).
    
    Error messages are better, but may still be misleading (e.g. they can
    report an unused value in function "foo/1", when the value was in fact
    defined inside a block "bar"). This is helped a bit by the fact that the
    error trace includes line and character number, so it will be obvious
    inside which block the error originates (or rather - it *should* be
    obvious).
