arm: [MVE intrinsics] add support for MODE_r
A few intrinsics have an additional mode (MODE_r), which does not
always support the same set of predicates as MODE_none and MODE_n.
For vqshlq they are the same, but for vshlq they are not.
Indeed we have:
vqshlq
vqshlq_m
vqshlq_n
vqshlq_m_n
vqshlq_r
vqshlq_m_r
vshlq
vshlq_m
vshlq_x
vshlq_n
vshlq_m_n
vshlq_x_n
vshlq_r
vshlq_m_r
This patch adds support for it.
