intel/elk: List all instructions that have BranchCtrl bit

Browse source 
Previously this bit was not clearly documented in PRMs, but gfx12 PRMs
finally list all the instructions where it is present.

Although it's unclear if it's functional for anything other than "if",
"else", and "goto", we probably still should acknowledge its existence
in other instructions.
