Revert part of a fix that used InstructionDeleter consistently during ConstantPropagation. This had a side effect of removing more dead code at -Onone. For some reason, that breaks SIL linkage. This showed up when rebuilding the Foundation module against a debug (-Onone) standard library, and verifying Data.InlineData.subscript.getter. Fixes rdar://85809683 (Swift CI: SIL verification failed: external declarations of SILFunctions with shared visibility is not allowed: SingleFunction || !hasSharedVisibility(RefF->getLinkage()) || RefF->hasForeignBody())

@swift-ci smoke test and merge |
