Removes a `copy_block` if its only uses, beside ownership instructions, are callees of function calls ``` %2 = copy_block %0 %3 = begin_borrow [lexical] %2 %4 = apply %3() : $@convention(block) @noescape () -> () end_borrow %3 destroy_value %2 ``` -> ``` %4 = apply %0() : $@convention(block) @noescape () -> () ``` rdar://118521396

/// INSTRUCTION_SIMPLIFICATION(Inst)
|
|
/// Defines an instruction simplification which is implemented in swift and is
|
|
/// run by the SILCombiner.
|
|
/// 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
|
|
/// `registerForSILCombine`.

|
|
|
/// INSTRUCTION_SIMPLIFICATION_WITH_LEGACY(Inst)
|
|
/// Like INSTRUCTION_SIMPLIFICATION, but also runs the legacy `visitInst`
|

/// implementation in SILCombine.
