[PATCH] D107305: [GlobalISel] Combine G_ASSERT_*EXT + G_LOAD -> G_S/ZEXTLOAD

[Amara Emerson via Phabricator via llvm-commits]

I don't think this is right. G_ASSERT_SEXT is supposed to only provide information for optimizations about the bits of the source. Using it to justify transforming the source seems the wrong place to fix it. We should be emitting the right kind of load in call lowering.
