[mlir] Fix region simplification bug when later blocks use prior block argument values (#97960)
This fixes #94520 by ensuring that any if any block arguments are being
used outside of the original block that the block is not considered a
candidate for merging.
More details: the root cause of the issue described in #94520 was that
`^bb2` and `^bb5` were being merged despite `%4` (an argument to `^bb2`)
was being used later in `^bb7`. When the block merge occurred, that
unintentionally changed the value of `%4` for all downstream code. This
change prevents that from happening.
