default boolean isFall() {
			return false;
		}
Indicates whether this branch represents a fall-through case.

<p>
Note that the {@link #from()} may not be an actual branching p-code op when
{@code isFall} is true. A "fall-through" branch happens in two cases. First, and most
obvious, is to describe the fall-through case of a {@link PcodeOp#CBRANCH conditional
branch}. Second is when for a p-code op the immediately precedes the target of some other
branch. That branch causes a split in basic blocks, and so to encode the fall through
from that op into the basic block immediately after, a fall-through branch is added.

@return true if this branch is the fall-through case.
