Branch Consistent conditionally to a label at a PC-relative offset, with a hint that this branch will behave very consistently and is very unlikely to change direction.

| <cond> |
Is one of the standard conditions, encoded in the "cond" field in the standard way. |
| <label> |
Is the program label to be conditionally branched to. Its offset from the address of this instruction, in the range +/-1MB, is encoded as "imm19" times 4. |
if ConditionHolds(condition) then boolean branch_conditional = TRUE; BranchTo(PC[] + offset, BranchType_DIR, branch_conditional);
