x86: Add support routines to convert between x87 tag formats
This changeset adds the convX87XTagsToTags() and convX87TagsToXTags() which convert between the tag formats in the FTW register and the format used in the xsave area. The conversion from to the x87 FTW representation is currently loses some information since it does not reconstruct the valid/zero/special flags which are not included in the xsave representation.
