The following macros are activated when the compiler is targeting SVE
with the option `-msve-vector-bits=<N>`:

1. __ARM_FEATURE_SVE_VECTOR_OPERATORS
2. __ARM_FEATURE_SVE_PREDICATE_OPERATORS

The behavior implied by the macros is described in sections 3.7.3.3
and 3.7.3.4 respectively of the SVE ACLE (Version 00bet6) that can be
found at https://developer.arm.com/documentation/100987/latest
