x86: Remove direct access to internal x86 descriptor fields

Hi -

This patch set aims to remove the direct access to the 'a' and 'b' fields of 32-bit x86 descriptors. Static inline getters/setters are provided.

This is a resumbmit of a patch set I submitted several months ago[1]. My last patch set was a bit large, so I've tried to take a smaller bite this time and slowly build the cleanup effort over a series of patch sets.

Any and all comments, suggestions, and questions are welcome.

Thanks,
Joe Damato
