Patch to fix 32-bit error on splititng loading 0 into VSX register
After this patch was installed, it was discovered that in 32-bit if the
compiler decides to load 0 into a VSX register, the compiler will complain when
it tries to split the load into two separate insns (for each gpr), and it can't
allocate a temporary GPR after reload.
