Add support for decoding the new branch control bit. I saw two things wrong with
the existing code.
1. It didn't bother trying to decode the bit.
- While we do not *intentionally* emit this bit today, I think it's interesting
to see if we somehow ended up with the bit set. It may also be useful in the
future.
2. It seemed to be the wrong bit.
- The docs are pretty poor wrt which bit this actually occupies. To me, it
/looks/ like it should be bit 28. I am not sure where Ken got 30 from. I
verified it should be 28 by looking at the simulator code.
I also added the most basic support for GOTO simply so we don't need to remember
to change the function in the future.
v2:
Move the branch_ctrl check out of the if gen >= 6 check to make it more
readable. (Matt)
ENDIF doesn't have branch_ctrl (Matt + Ken)

The parameter is an int16_t, and we're check that it's value will fit in
16-bits. Yes, the value that is stored in 16-bits will surely fit in
16-bits.

These got lost in the big brw_inst shakeup.

For now nothing uses this, but we can incrementally convert.

Use this an an opportunity to clean up the formatting of some old code
(brw_ADD, for instance).

This is similar to gen8_instruction, and will eventually replace it.
For now nothing uses this, but we can incrementally convert.
The new API takes the existing brw_instruction pointers to ease
conversion; when done, we can simply drop the old structure and rename
struct brw_instruction -> brw_inst.
v2: (by Matt Turner) Make JIP/UIP functions take a signed argument.
v3: (by Kenneth Graunke)
- Make Gen4-6 jump target functions take a signed argument.
- Fix indirect align1 AddrImm bits on Gen4-7.
- Fix SFID on Sandybridge to use bits 27:24.
