[RFA] Fix i386-sse.exp regression on Darwin

[Tristan Gingold <gingold@adacore.com>]

Hi,

xmm0 is a scratch register for the Darwin/i386 ABI and therefore may  
be destroyed by calling a function.
This patch fix a regression on Darwin by replacing a function call by  
a asm nop.  The only purpose of the
function call was to be able to put a breakpoint.

Tristan.
