This patch series optimizes type traits performance by implementing
built-in type traits and using them in libstdc++.
Changes in v19:
* Fixed a typo.
* Rebased on top of trunk.
* Improved clarity of the commit message.
Changes in v18:
* Removed all RID values for built-in traits and used cik_trait
instead.
* Improved to handle the use of non-function-like built-in trait
identifiers.
* Reverted all changes to conflicted identifiers with new built-ins
in the existing code base.
Changes in v17:
* Rebased on top of trunk.
* Improved clarity of the commit message.
* Simplified Make-lang.in.
* Made ridpointers for RID_TRAIT_EXPR and RID_TRAIT_TYPE empty.
Changes in v16:
* Rebased on top of trunk.
* Improved clarity of the commit message.
* Simplified Make-lang.in and gperf struct.
* Supply -k option to gperf to support older versions than 2.8.
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.
