Fix a whole bunch of binary literals which were the wrong size. All were being silently zero extended to the correct width.
...
The commit after this changes { } and 0bxx literals to be of type bits<n> and not int. This means we need to write exactly the right number of bits, and not rely on the values being silently zero extended for us.

Remove the form field from Mips16 instruction formats and set things

up so that we can apply the direct object emitter patch. This patch
should be a nop right now and it's test is to not break what is already
there.
