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

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.
