re PR target/48551 (Following source code crashes the c++ compiler on coldfire platform.)

PR target/48551
* reload.h (struct target_reload): Make x_double_reg_address_ok
be per-mode rather.
* reload.c (find_reloads_address): Check if double_reg_address_ok
is true for the mode of the memory reference.
* reload1.c (init_reload): Initialize double_reg_address_ok for
each mode.
PR target/48551
* gcc.target/m68k/pr48551.c: New test.
