commit r13-6090-g53b55701aed6896f456cdec7997ac6bbef1d6074

libstdc++: Annotate most lambdas with always_inline
All of the annotated lambdas are simply a necessary means for
implementing these functions and should never result in an actual
function call. Many of these lambdas would go away if C++ had better
language support for packs.
