cmd/internal/obj reconverted using rsc.io/c2go rev 2a95256.
- Brings in new, more regular Prog, Addr definitions
- Add Prog* argument to oclass in liblink/asm[68].c, for c2go conversion.
- Update objwriter for change in TEXT size encoding.
- Merge 5a, 6a, 8a, 9a changes into new5a, new6a, new8a, new9a (by hand).
- Add +build ignore to cmd/asm/internal/{addr,arch,asm}, cmd/asm.
They need to be updated for the changes.
- Reenable verifyAsm in cmd/go.
- Reenable GOOBJ=2 mode by default in liblink.
All architectures build successfully again.

cmd/internal/obj reconverted using rsc.io/c2go rev 40275b8.
All Prog*s need Ctxt field set so that the printer can tell
which architecture the Prog belongs to.
Use ctxt.NewProg consistently for this.

Using rsc.io/c2go repo revision 60c9302.
- Export a few symbols needed by assemblers.
- Implement Getgoroot etc directly, and add Getgoversion.
- Removes dependency on Go 1.4 go/build.
- Change magic history name <no name> to <pop>
The <pop> change requires adjustment to the liblink serializer.

This CL adds the real cmd/internal/obj packages.
Collectively they correspond to the liblink library.
The conversion was done using rsc.io/c2go's run script
at rsc.io/c2go repo version 706fac7.
This is not the final conversion, just the first working draft.
There will be more updates, but this works well enough
to use with go tool objwriter and pass all.bash.

cmd/internal/obj is the name for the Go translation of the C liblink library.
cmd/objwriter is the name of a Go binary that runs liblink's writeobj function.
When the bulk of liblink has been converted to Go but the assemblers and
compilers are still written in C, the C writeobj will shell out to the Go objwriter
to actually write the object file. This lets us manage the transition in smaller
pieces.
The objwriter tool is purely transitional.
It will not ship in any release (enforced in cmd/dist).
Adding a dummy program and some dummy imports here so that we
can work on the bootstrap mechanisms that will be necessary to build it.
Once the build process handles objwriter properly,
we'll work on the actual implementation.
