[SLP] Increase UsesLimit to 64 (#99467)
Since commit 82b800ecb35fb46881aa52000fa40b1b99aa654e addressed the
issue #99327 , we see some performance regression (13%) on some
verilator generated C++ code. This is because the UsesLimit is set to 8,
which is too small for the verilator generated code. I have analyzed the
need for the UsesLimit from [1] and found that the UsesLimit should be
at least 64 to cover most of these cases. Thus, This patch increases the
UsesLimit to 64.
