BOLT used to mark multi-entry functions non-simple in non-relocation mode with the reasoning that we can't move them due to potentially undetected references. However, in aggregation mode it doesn't apply as BOLT doesn't perform optimizations. Relax this constraint in case of an aggregation job. Test Plan: added entry-point-fallthru.s
