   SVN rev 180756 on 2008-07-23 11:37:20Z by luoqi
   
   Unbreak cc -pg support on i386. In gcc 4.2, %ecx is used as the arg pointer
   when stack realignment is turned on (it is ALWAYS on for main), however
   in a profiling build %ecx would be clobbered by mcount(), this would lead
   to a segmentation fault when the code tries to reference any argument.
   This fix changes mcount() to preserve %ecx.
