Are there any plans on adding upstream runtime testing for EVL vectorization to guard against regressions? 

We really should have upstream end-to-end testing that enables the EVL vectorization path and does a stage2 build + llvm-test-suite to catch regressions (similar to how SVE enabled bots were added when scalable vector support was added IIRC)
