JIT: fix scalability issue in redundant branch optimizer (#66259)

In methods with long skinny dominator trees and lots of redundant branches
the jit can spend too much time trying to optimize the branches.

Place a limit on the number of redundant branches with matching VNs that
the jit will consider for a given branch.

Fixes #66067.
