I'm committing this one as obvious once my powerpc64le-linux bootstrap
and regression check completes. It fixes hundreds of rtl checking
testsuite errors like the following:
gcc.c-torture/compile/pr39943.c:6:1: internal compiler error: RTL check: expected elt 0 type 'e' or 'u', have 'E' (rtx unspec) in insn_is_swappable_p, at config/rs6000/rs6000.c:40678
* gcc/config/rs6000/rs6000.c (insn_is_swappable_p): Properly
look inside UNSPEC_VSX_XXSPLTW vec.

Good catch, Alan, this one is my fault. I'll handle the backports to the 5 and 6 branches.
