  -----------
  [CodeGen] Fix profiled triangular CFG threshold in MachineBlockPlacement (#188752)

Fix an assertion failure in MachineBlockPlacement for profiled
triangular CFGs with large -profile-likely-prob values.

The existing triangular-CFG threshold scaling can produce a
BranchProbability greater than 1. Capping to `BranchProbability(100,
100)` added.
