Translate pc to bci

[Tom Rodriguez]

A pc may translate to multiple bcis because of inlining and that's  
described by a ScopeDesc.  Use method::scope_desc_at to find the  
ScopeDesc for a pc and get the bci from the from that.  If you want  
the full chain then use ScopeDesc::sender() to get the caller.
