[v14,00/40] Optimize type traits performance

  This patch series optimizes type traits performance by implementing
built-in type traits and using them in libstdc++.

Changes in v14:

	* Attached the benchmark results of the enum rid change

Changes in v13:

	* Fixed ambiguous commit message and comment

Changes in v12:

	* Evaluated all paddings affected by the enum rid change

Changes in v11:

	* Merged all patches into one patch series
	* Rebased on top of trunk
	* Unified commit message style
	* Used _GLIBCXX_USE_BUILTIN_TRAIT
