copy_from_gs() and copy_to_gs() are unused in the boot code. They have
actually never been used -- they were always commented out since their
addition in 2007:
5be865661516 ("String-handling functions for the new x86 setup code.")
So remove them -- they can be restored from history if needed.

This reverts commit 28b48688 ("x86, boot: use .code16gcc instead
of .code16").
Versions of binutils older than 2.16 are already not working, so this
workaround is no longer necessary either. At the same time, some of
the transformations that .code16gcc does can be *extremely*
counterintuitive to a human programmer.
