That sounds worthwhile for critical paths.

How about reverting the build_string change, and defining a new
inline function build_literal intended for when the argument is a
string literal and for when speed is more important than conserving
code space?  That would give us speed where speed matters and where
we know it'll be faster, while avoiding code bloat otherwise.
build_string and  build_literal would have identical semantics,
but different performance properties.
