middle-end: replace GET_MODE_WIDER_MODE with GET_MODE_NEXT_MODE
After the fix to the addsub patch yesterday for bootstrap I had only regtested on x86.
While looking today it seemed the new tests were failing, this was caused
by a change in the behavior of the GET_MODE_WIDER_MODE macro on trunk.
gcc/ChangeLog:
* match.pd: Replace GET_MODE_WIDER_MODE with
custom code.
