<pre>The information about load source should be used to produce load+mask where
currently concatenated loads produced, for example a known size array:
#include <cstring>
#include <cstdint>
#include <cstddef>
std::uint32_t loadu24(std::byte const(&src)[10])
{
std::uint32_t result = 0;
std::memcpy(&result, src, 3);
return result;
}</pre>
