Public Attributes
ArgKind	kind = ArgKind::Direct
Type	coercedType = nullptr
	The ABI-coerced type, if different from the original.
llvm::Align	indirectAlign = llvm::Align(1)
	For Indirect: alignment of the pointed-to object.
bool	signExtend = false
	For Extend: whether to sign-extend (true) or zero-extend (false).
bool	canFlatten = true
	For Direct: whether a struct coercion can be flattened into individual register-width arguments.
bool	byVal = false
	For Indirect: whether the callee gets ownership (byval).
