This patchset implements the LOAD PAIR FROM QUADWORD and STORE PAIR TO QUADWORD instructions. The corresponding patches have been in my previous patchset and the pull request from Richard, but they failed to build on a host without atomic128 support.
This new version fixes that. It has to be applied over the pull request as it makes uses of the check_alignment function. Finally the latest patch fixes a lack of alignement check in CDSG, discovered as I used it as an example about how to properly handle hosts without atomic128 support.
