The gdbstub implementation for the Sparc architecture would
incorrectly calculate the the floating point register offset.
This resulted in, for example, registers f32 and f34 to point to
the same value.
The issue was caused by the confusion between even register numbers
and even register indexes. For example, the register index of f32 is 64
and f34 is 65.
