Use inline functions rather than macros for cpu_ld/st accessors for the *-user configurations, as we already do for softmmu. This has a two advantages: * we can actually typecheck our arguments * we don't need to leak the _raw macros everywhere Since the _kernel functions were only used by target-i386/seg_helper.c, put the definitions for them in that file too. (It already has the similar template include code to define them for the softmmu case, so it makes sense to have it deal with defining them for user-only.)
