Revert "[AssumptionCache] caches @llvm.experimental.guard's"
This reverts commit f9599bbc7a3f831e1793a549d8a7a19265f3e504.
For some reason it caused us a huge compile time regression in downstream
workloads. Not sure whether the source of it is in upstream code ir not.
Temporarily reverting until investigated.
