-----------
[mlir][SCF] Do not access erased operation in scf.while lowering
Do not access the erased cf.cond_br operation in the lowering pattern. That won't work anymore in a One-Shot Dialect Conversion and triggers a use-after-free sanitizer error.
After the One-Shot Dialect Conversion refactoring, a ConversionPatternRewriter will behave more like a normal PatternRewriter.
