[SimplifyCFG] Fix SimplifyCFG pass to skip folding when both blocks contain convergence loop/entry intrinsics. (#166452) ...

Fixes a bug https://github.com/llvm/llvm-project/issues/165642. [Similar
fix](https://github.com/llvm/llvm-project/pull/165643) is being made in
`IndVarSimplify` pass to account for convergence tokens.

[LLVM
Spec](https://llvm.org/docs/ConvergentOperations.html#llvm-experimental-convergence-loop)
states that only a single loop / entry convergence token can be included
in a basic block.

This PR fixes the issue in `SimplifyCFG` pass so that when a basic block
and its predecessor both contain such convergence intrinsics, it skips
merging the two blocks.
