- don't manually truncate values before passing them to TypedData._[set|get]<Type> - these methods already have truncating semantics; - don't call into runtime for endianess conversion, implement it in pure Dart instead (with an intent to provide optimized version on platforms that support fast byte-swapping instructions); - force inlining of these methods (change the order of checks in the ShouldWeInline to guarantee inlining of whitelisted methods). Unrelated change: - tweak output of Function::CheckSourceFingerprint to be immediately copy&paste useful.
