Expand description

This is an implementation detail of `crate::ptr::read` and should not be used anywhere else. See its comments for why this exists.

This intrinsic can only be called where the pointer is a local without projections (`read_via_copy(ptr)`, not `read_via_copy(*ptr)`) so that it trivially obeys runtime-MIR rules about derefs in operands.
