[1/3][aarch64] Add vec_widen patterns to aarch64
Add widening add and subtract patterns to the aarch64
backend. These allow taking vectors of N elements of size S
and performing and add/subtract on the high or low half
widening the resulting elements and storing N/2 elements of size 2*S.
These correspond to the addl,addl2,subl,subl2 instructions.
gcc/ChangeLog:
* config/aarch64/aarch64-simd.md: New patterns
vec_widen_saddl_lo/hi_<mode>.
