      If we discover a known call, and that call has a source transform or is a
      	
      conditional, then we replace the function with a lambda that
      just calls the function again.  This gives IR1 conversion another chance
      to permute the call.
      Changed IR1 transforms to test the function type with :STRICT-RESULT T
      since this is almost always what you want when writing a transform.
      In constant folding, if the call returns multiple values, change
      the function to a call to VALUES, rather than just blowing off
      constant folding.
      Added DELETE-LET which deletes the bind node for a let when all 
      its variables are deleted.  This cleans up the IR1 a great deal, enabling
      some optimizations.
      Added an IR1 optimizer for VALUES that converts MV-BIND/VALUES into a
      LET (as long as the VALUES is the only use of the values continuation.)
      This helps optimization of the results of IR1 transforms for multiple
      value functions.
      Added a IR1 transform for VALUES that discards all but the first
      value when the context is not a multiple-value receiver.

      Enhanced let optimization: · e6cccc13

      Now we substitute for global function variables when the reference isn't
      :notinline.
      Also, single-reference let variables can be squeezed out by replacing
      the ref's value continuation with the argument continuation.  The biggest
      advantage of this is that it allows output type assertions on the reference
      to be seen by the argument, which helps INCF, PSETQ, etc.
