arm: [MVE intrinsics] Fix support for loads [PR target/114323]
The testcase in this PR shows that we would load from an uninitialized
location, because the vld1 instrinsics are reported as "const". This
is because function_instance::reads_global_state_p() does not take
CP_READ_MEMORY into account. Fixing this gives vld1 the "pure"
attribute instead, and solves the problem.
