There was a problem hiding this comment.
Worked with @SingleAccretion on this fix.
The premise is that IsAlwaysAliveInMemory checks both lvLiveInOutOfHndlr and lvSpillAtSingleDef. The latter is only set in LSRA and shouldn't have any significance with regards to side effect checking since such spills can't interfere.
This solves the inconsistency between the check in lowering and the assert in codegen.
