Tom Stellard 2aab32cade R600/SI: Fix indirect addressing with a negative constant offset ...

When the base register index of the vector plus the constant offset
was less than zero, we were passing the wrong base register to the indirect
addressing instruction.

In this case, we need to set the base register to v0 and then add
the computed (negative) index to m0.
