Don't segfault on bare return statements.
...
I will probably need to do something about the required operand for v6
progs, but this will do for now.

Add "debug" diagnotic printing, and use it.
...
Debug diagnostics are silent for verbosity levels less than 1.

Ensure functions are always properly terminated.
...
Control that reaches the end of a function must see a return statement.

Conditional branches and goto now go to the correct location.

Get assignments to .return working.
...
I really do not like the mechanism I currently use for handling pointer
derefences vs pointer assignments, but this will have to do for now until
I can get qfcc producing code again.

Get statments being emitted to the code segment.
...
The first function seems to work fine, but there's a problems with the
scope of params causing params to get their knickers in a twist (tangled
linked list).

"return" falling through to "goto" was bad news :)

Nuke bind expressions.
...
Since I'm planning on implementing CSE and other optimizations, they're
rather redundant (and I'm having trouble getting them to work).
