River Riddle	438dc176b1	Remove the need to convert operations in regions of operations that have been replaced. ... When an operation with regions gets replaced, we currently require that all of the remaining nested operations are still converted even though they are going to be replaced when the rewrite is finished. This cl adds a tracking for a minimal set of operations that are known to be "dead". This allows for ignoring the legalization of operations that are won't survive after conversion.

River Riddle	49b29dd186	Add a PatternRewriter hook for cloning a region into another. ... This is similar to the `inlineRegionBefore` hook, except the original blocks are unchanged. The region to be cloned *must* not have been modified during the conversion process at the point of cloning, i.e. it must belong an operation that has yet to be converted, or the operation that is currently being converted.

River Riddle	9619ba10d4	Add support for multi-level value mapping to DialectConversion. ... When performing A->B->C conversion, an operation may still refer to an operand of A. This makes it necessary to unmap through multiple levels of replacement for a specific value. PiperOrigin-RevId: 269367859	2019-09-16 10:38:19 -07:00
