fix pretty bad bug in alias analysis

Browse source 
When a temporary marked local is escaping,
the whole slot must be marked as such.  To
solve this, Alias now holds a pointer to
the alias information of the slot.  For
simplicity of the code, this pointer is
always valid and fetching ->type out of it
is meaningful.
