Revert "[MLIR] Fuse locations of merged constants (#74670)"
This reverts commit 87e2e89019ec4405fa47c3b4585be4e67473b590.
and its follow-ups 0d1490f09f23bf204b714c3c6ba5e0aaf4eeed9a (#75218)
and 6fe3cd54670cae52dae92a38a6d28f450fe8f321 (#75312).
We observed significant OOM/timeout issues due to #74670 to quite a few
services including google-research/swirl-lm. The follow-up #75218 and
#75312 do not address the issue. Perhaps this is worth more
investigation.
