"""makes a 2-deep copy of the functions, global invariants, novars
within C6.
Used to initialize a C6 for a function body for function, funname
Makes store and heap empty and places dummy scalar and array values
in store based on scalars and arrays . Sets rels to []
Subtracts localglobals from ``novars'' list to denote that
these vars are mutable
Revises globalinvs list, removing brokeninvariants that are no longer
invariants because their vars are mutable
Places brokeninvariants into brokeninvs list
params: C6;
funname : name of function
scalars: vtree list of scalar vars;
arrays: vtree list of array vars
localglobals : vtree list of global vars that can be mutated
brokeninvariants: invariants that mention
local globals, a btree list
