rs6000: MMA built-in dies with incorrect sharing of tree nodes error

When we expand our MMA built-ins into gimple, we erroneously reused the
accumulator memory reference for both the source input value as well as
the destination output value.  This led to a tree sharing error.
The solution is to create separate memory references for the input
and output values.

Fixed on trunk.  I'll backport the fix to GCC 10 after a little burn in on
trunk.
