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.

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.

In the process, I made error handling in the statement
compiler much saner. Instead of separately tracking various
error flags with weird relations, I just track if any error
messages have been produced.

statement compiler will be fixed in a later CL.
The input and output of the expression compiler are now
clearly distinguished. In the process, I made the individual
expression compilers operate on the compiled form of their
children instead of AST nodes. As a result, there are now
fewer places where I hand-craft intermediate expression nodes.
The diff looks scarier than it is, mostly because exprCompiler
has been split into the input and output types, resulting in
lots of little renames.
