[PATCH] D12975: [Polly] De-LICM (WIP)

[Michael Kruse via llvm-commits]

Meinersbur added a comment.

Current status:
Works fine on the licm_reduction.ll test case, but has one redundant MustWriteAccess which already has been there before.
None of the other tests or code generation has been worked on yet.
Currently only code for the case that the value is written back to the array. Hoisting of reads must be handled with additional code.
There are many operations based on DenseSets of edges, but I I don't know how to check lifetime overlaps more efficiently.
