Fix PR middle-end/98099
this replaces the ICE by a sorry message for the use of reverse scalar
storage order with 128-bit decimal floating-point type on 32-bit targets.
gcc/ChangeLog:
PR middle-end/98099
* expmed.c (flip_storage_order): In the case of a non-integer mode,
sorry out if the integer mode to be used instead is not supported.
gcc/testsuite/ChangeLog:
* gcc.dg/pr98099.c: New test.
