[RFC] sim/sh: Fix compile warnings for 64-bit build hosts

[Kevin Buettner <kevinb@redhat.com>]

Any comments on the following patch?

It fixes a bunch of warnings when building on a 64-bit host.  Here
are a few of them:

./code.c:93: warning: cast from pointer to integer of different size
./code.c:215: warning: cast from pointer to integer of different size
./code.c:230: warning: cast from pointer to integer of different size

	* sh/interp.c (MA): Adjust cast to avoid warning on 64-bit hosts.
