* When constructing instructions which have substitution maps: initialize those with the canonical SubstitutionMap * Also initialize SILFunction::ForwardingSubMap with the canonical one Non-canonical substitution maps may prevent generic specializations. This fixes a problem in Embedded Swift where an error is given because a function cannot be specialized, although it should. https://github.com/swiftlang/swift/issues/83895 rdar://159065157
