Proposed resolution:
This wording is relative to N5014.
In subclause [simd.loadstore] replace all occurrences of
R(first, n)
by
R(first, static_cast<size_t>(n))

Currently, `simd::unchecked_load`/`partial_load`/`unchecked_store`/`partial_store` construct a `span` via `span(first, n)` when taking an iterator `first` and its difference type `n`.
However, the construction is ill-formed when the difference type is an integer-class type; we should perform an explicit casting here.
