Helper to emit outlined function for 'target' directive.

Parameters

D	Directive to emit.
ParentName	Name of the function that encloses the target region.
OutlinedFn	Outlined function value to be defined by this call.
OutlinedFnID	Outlined function ID value to be defined by this call.
IsOffloadEntry	True if the outlined function is an offload entry.
CodeGen	Lambda codegen specific to an accelerator device. An outlined function may not be an entry if, e.g. the if clause always evaluates to false.
