Mainline Ada bootstrap is currently broken on Solaris 8 and 9/x86 with
Sun as:

Assembler: a-strunb.adb
	"/var/tmp//cc6ZxWWa.s", line 2395 : Syntax error
	"/var/tmp//cc6ZxWWa.s", line 2591 : Syntax error
make[7]: *** [a-strunb.o] Error 1

The problem is that s-atocou-x86.adb uses lock incl resp. lock decl,
where older Sun as requires lock; incl.  This is exactly what %; was
introduced for, which is already used in i386/sync.md.

The following patch uses it and allowed i386-pc-solaris2.[89] bootstraps
to complete.  Testing is currently running, and I'll also bootstrap with
gas instead of as once that's finished.

Ok for mainline if those tests pass?

Thanks.

	* s-atocou-x86.adb (Decrement): Use %;.
	(Increment): Likewise.
