Log:
Use extract_bit_field_as_subreg for vectors

extract_bit_field_1 tries to use vec_extract to extract
part of a vector.  However, if that pattern isn't defined
or if the operands aren't suitable, another good approach
is to try a direct subreg reference.  This is particularly
useful for multi-vector modes on SVE (e.g. when extracting
one vector from an LD2 result).
