Call to the runtime to generate escaping variables and use the returned
address when accessing these variables.
Fix a couple of errors on the way. The rule for CALLstatic was missed
during the Aux refactor and OCONVNOP wasn't converted.

Add an additional int64 auxiliary field to Value.
There are two main reasons for doing this:
1) Ints in interfaces require allocation, and we store ints in Aux a lot.
2) I'd like to have both *gc.Sym and int offsets included in lots
of operations (e.g. MOVQloadidx8). It will be more efficient to
store them as separate fields instead of a pointer to a sym/int pair.
It also simplifies a bunch of code.
This is just the refactoring. I'll start using this some more in a
subsequent changelist.

ODCL nodes are used as the point where the variable is allocated in
the old pass. colas is irrelevant at this point of the compile. All
the checks on it happen at parse time and an ODCL node will have been
inserted right before it.

Revamp autogeneration. Get rid of gogenerate commands, they are more
trouble than they are worth. (If the code won't compile, gogenerate
doesn't work.)
Generate opcode enums & tables. This means we only have to specify
opcodes in one place instead of two.
Add arch prefixes to opcodes so they will be globally unique.
