x86/asm: Clean up frame pointer macros

The asm macros for setting up and restoring the frame pointer
aren't currently being used.  However, they will be needed soon
to help asm functions to comply with stacktool.

Rename FRAME/ENDFRAME to FRAME_BEGIN/FRAME_END for more
symmetry.  Also make the code more readable and improve the
comments.
