title: Where is the Rust intrinsic called "transmute" actually implemented?
body: <p>I'm trying to find the implementation for the Rust intrinsics, particularly the "transumte" intrinsic that takes one argument.</p>
  
  <p>I've seen the following code in cast.rs, but as you can see, it merely delegates to some other implementation of transmute.</p>
  
  <pre><code>#[inline]
  pub unsafe fn transmute&lt;L, G&gt;(thing: L) -&gt; G {
      intrinsics::transmute(thing)
  }
  </code></pre>
  
  <p>Where is the actual implementation for intrinsics, especially the transmute intrinsic?</p>
