gfortran.dg/class_array_9.f03 ICEs for a while on sh4-unknown-linux-gnu.

FAIL: gfortran.dg/class_array_9.f03  -O0  (internal compiler error)

gfortran.log says:

internal compiler error: in change_address_1, at emit-rtl.c:2006

Here is a gdb's backtrace for f951:

     (nil))

Looks that something wrong happens during reload and it requests
an illegal memory address r14+4 for SFmode on SH.
It started to fail between trunk revision 185498 and 185552.
Perhaps related to the changes for PR target/50751.
