Seen also on powerpc64-linux.  The problem here is that the vsx_splat_V2DF/V2DI
load and store instructions only support mem[reg] or mem[reg+reg] addressing,
but the MEM mode is not a vsx vector mode.  So reg_offset_addressing_ok_p used
in rs6000_legitimate_address_p and other address predicates returns true,
wrongly allowing lo_sum addresses.

 Could this pr be related to pr45585?

The fix for pr45585 does not works for this pr.

I guess, it's a DI/DF problem...
If so, the code the vectorizer produces seems to be ok:

vector(2) real(kind=8) vect_cst_.14;
real(kind=8) reciptmp.5;
real(kind=4) dtime;
real(kind=8) D.1357;
...

D.1357_12 = (real(kind=8)) dtime_11(D);
reciptmp.5_60 = 1.0e+0 / D.1357_12;
...
vect_cst_.14_51 = {reciptmp.5_60, reciptmp.5_60};


VDI first shows up in ira.
