[llvm-branch-commits] [mlir] [mlir][LLVM] erase call mappings in forgetMapping() (PR #84955)

[Tom Eccles via llvm-branch-commits]

https://github.com/tblah created https://github.com/llvm/llvm-project/pull/84955

It looks like the mappings for call instructions were forgotten here. This 
fixes a bug in OpenMP when in-lining a region containing call operations 
multiple times.

OpenMP array reductions 4/6
