Fix the problems exposed by the callingconv1.d test case.
The first was that unless otherwise specified, inputs are assumed to be in
registers even if they specify a "matching output" that's in memory.
While testing that fix, I also ran into a bug causing the generated "matching
output" for any input was always the first one instead of the correct one.
