  -----------
  [mlir][LLVMIR] Fix a crash when `llvm.mlir.constant` fails to create an LLVM constant. (#224951)

Fix the `llvm.mlir.constant` translation to handle a failed
`getLLVMConstant()` conversion. The current code can pass a null
`llvm::Value` to users of the constant, causing an assertion. Check the
result of `getLLVMConstant()` and return failure when the conversion
fails.

Fixes #224815
