Subject: [PATCH] Fix internal compiler error with msmall-divides

This patch will fix the internal error microblaze_expand_divide function
which comes because of rtx PLUS where the mem_rtx is of type SI and the
operand is of type QImode. This patch modifies the mem_rtx as QImode and
Plus as QImode to fix the error.
