ffe83e582e Switch ogle over to the in-tree debug/proc package. Fix
debug/proc to install to the right place.  Delete the old
ptrace package.  The diff looks huge, but it's mostly
s/ptrace/proc/.

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.

c0dd9f526b Make the statement compiler not use the AST visitor.
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.

36eee6d1e1 Make the expression compiler not use the AST visitor. The
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.
