PATCH to real.c:do_multiply

- Subject: PATCH to real.c:do_multiply
I tracked down a recent bootstrap failure to our failure to initialize
u.canonical along with the rest of u.
Repeat after me: I will always use memset to initialize a struct. Trying
to initialize all members invariably breaks.
Booted and tested powerpc-linux-gnu, applied to trunk and tree-ssa.
