The two split patterns associated with
aarch64_ashr_sisd_or_int_<mode>3 split the instruction into a NEG
followed by an SHL. The split uses one of the input operands as a
scratch register to hold the output of the NEG resulting in register
corruption.
This patch adjusts the splits to use the output operand as the scratch
register.

Add alternative; make early clobber. Adjust both split patterns
to use operand 0 as the working register.
