264641711b Switch back to returning Value from the public expression
interface, but implement it better this time.  Also, work
around a 6g bug in asInterface.

3dfbfdabce Clean up the statement and expression public interfaces. The
only visible change is that evaluating an expression returns a
interface{} instead of a Value.

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.

fda0e78b23 fix line numbers, again.
if first function in file was dead code, it was being
discarded along with the file name information for that file.
leave the functions in the master function list longer:
let xfol take the dead code out of the code list,
and let span skip the unreachable functions during output.
