[llvm] Fixes inlining issue in armv7 (PR #169337)

Hi - What makes a feature invalid for inlining? If it disables the use of some instructions/registers? It would seem that many more features (including FeatureFP64 and FeatureD32) could be added to the list. Why is HasV8Ops there if HasV8_1aOps isn't? Why is FeatureDotProd, but not FeatureAES?

Can you add a test? Both for inlining a function with dotprod and for inlining _to_ a function with dotprod.
