This patch series optimizes type traits performance by implementing
built-in type traits and using them in libstdc++.
Changes in v15:
* Rebased on top of trunk
* Use gperf to look up traits instead of enum rid
Changes in v14:
* Added padding calculation to the commit message
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
