[PATCH] i386: generate better code around descriptor update and access functions

GCC can generate better code around descriptor update and access functions
when there is not an explicit "eax" register constraint.

Testing: You won't boot if this is messed up, since the TSS descriptor will be
corrupted.  Verified the assembler and booted.
