[PATCH] xfail ira-shrink-wrap-prep tests (PR87708)

[Segher Boessenkool]

After r265398, the ira-shrinkwrap-prep-[12].c tests fail on all
targets, because the IRA feature tested can only move hard registers
down, and we no longer have hard registers for the function parameters
at this stage.

Is this okay for trunk?
