With the change in the Solaris release model (no more major releases
like Solaris 12 but only minor ones like 11.4), the Solaris 12
references in GCC need to be adapted.

Turn aarch64_simd_bsldi_internal in to an insn_and_split that
knows to split back to integer operations if the register allocation
falls that way. Do this to avoid having to move between integer and
Advanced SIMD register files just for a single BSL.
