Add ebx to the i386 clobber list for MPI assembly

Browse source 
This fix adds the ebx register to the clobber list for the i386 inline assembly
for the multiply helper function.

ebx was used but not listed, so when the compiler chose to also use it, ebx was
getting corrupted. I'm surprised this wasn't spotted sooner.

Fixes Github issues #1550.
