e98412290e interpreter checkpoint. 
* generate different versions of binary operators
    for each size of int and float, so that proper
    truncating happens after each operation to
    simulate the various sized ops.
  * add slice expressions
  * publish World.CompileStmtList, CompileDeclList, CompileExpr
  * handle type-less expressions in CompileExpr

4211384976 Switch ogle to in-tree gosym package. Delete my private sym 
package.  If a Sym is a function symbol, include a reference
to the Func so it's easily accessible when you're traversing
the list of all symbols.  This diff is more interesting than
the proc switch because the gosym interface differs from the
old sym interface.

da4a22993e Fix declared and not used errors and unused import errors in 
the interpreter and update code to use ast.BasicDecl and
multi-type switch.  There are still a lot of "switch _ :=
x.(type)" that should make use of the new type switch syntax,
but those will be a different CL.

155fe7925b Add stack frame support. Architectures are now responsible 
for decoding closures.  There is now no notion of a current OS
thread, though that needs to come back in the form of a
current Go thread.  As a result, Process now implements Peek
and Poke and maps them to any stopped OS thread, since they
all share the address space anyways.
