Description of Changes
Reworks the handling of branches (with links) in delay slots and chains of 3 or more branches.
Rationale behind Changes
Linking inside delay slots wasn't..right (or at least the flow is strange), but chaining 3 or more branches together just didn't work correctly, at all, the fact games worked was by sheer fluke.
Suggested Testing Steps
Test any games that do branches/jumps (especially ones that link like BAL or JALR!) in delay slots, and especially games that to "branch, branch, branch!"
