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.
