Add pass to promote sret.

This pass transforms
%struct._Point = type { i32, i32, i32, i32, i32, i32 }
define internal void @foo(%struct._Point* sret %agg.result)
into
%struct._Point = type { i32, i32, i32, i32, i32, i32 }
define internal %struct._Point @foo()
This pass updates foo() clients appropriately to use
getresult instruction to extract return values.
This pass is not yet ready for prime time.
