[PATCH] D13606: [Introduction] Redundant load reduction with invariant intrinsics

[Daniel Berlin via llvm-commits]

I'm with Philip on this one.
This patch looks like it  can be split up.
As a rule, you don't have to make everything go at once, you can do it
piece by piece.

(IE it's fine to modify one transform/analysis pass, even if nothing
but tests use it yet, and then add the use in a separate patch).

More to the point, the feedback you are getting says: "If you want
this reviewed by reviewers, you should split it up more".
So unless you can point to concrete reasons it can't be split up, you
should do that.
