`BUILD_INTERPOLATION` and `BUILD_TEMPLATE` perform unnecessary refcount operations

Feature or enhancement

Proposal:

BUILD_INTERPOLATION and BUILD_TEMPLATE call _PyInterpolation_Build and _PyTemplate_Build respectively, and then decref their arguments. All other BUILD instructions call a "steal" function, to avoid the unnecessary incref then decref. BUILD_INTERPOLATION and BUILD_TEMPLATE should do the same.

Has this already been discussed elsewhere?

This is a minor feature, which does not need previous discussion elsewhere

BUILD_INTERPOLATION と BUILD_TEMPLATE の命令ハンドラー、および _PyInterpolation_Build と _PyTemplate_Build のエントリーポイントから始めます。これらを他の BUILD 命令の steal 関数と比較します。これらの命令が不要な incref/decref 操作を回避すれば完了です。
