x86: introduce save_rest and restructure the PTREGSCALL macro in entry_64.S
Impact: cleanup
The save_rest function completes a partial stack frame for use
by the PTREGSCALL macro. This also avoids the indirect call in
PTREGSCALLs.
This adds the macro movq_cfi_restore to hide the CFI_RESTORE
annotation when restoring a register from the stack frame.
