[PATCH] i386: system.h: remove extra semicolons and fix order

include/asm-i386/system.h has trailing semicolons in some of the
macros that cause legitimate code to fail compilation, so remove
them. Also remove extra blank lines within one group of macros.

And put stts() and clts() back together; they got separated somehow.
