x86/entry/64: Merge SAVE_C_REGS and SAVE_EXTRA_REGS, remove unused extensions
All current code paths call SAVE_C_REGS and then immediately
SAVE_EXTRA_REGS. Therefore, merge these two macros and order the MOV
sequeneces properly.
While at it, remove the macros to save all except specific registers,
as these macros have been unused for a long time.
