We insert end_cow_mutation_addr for lifetime dependent values dependent on mutable addresses. end_cow_mutation_addr can be simplified to end_cow_mutation after other optimizations like inlining, specialization etc This PR adds an instruction simplification to transform end_cow_mutation_addr to end_cow_mutation. This can enable array optimizations which look for end_cow_mutation.

/// INSTRUCTION_SIMPLIFICATION(Inst)

/// Defines an instruction simplification which is implemented in swift and is

/// The \p Inst argument specifies the instruction class.

|
///
|
|
/// No further code is need on the C++ side. On the swift side an instruction

/// simplification must be registered for the instruction class with

/// INSTRUCTION_SIMPLIFICATION_WITH_LEGACY(Inst)

/// Like INSTRUCTION_SIMPLIFICATION, but also runs the legacy `visitInst`
