Log:
don't redescribe bitcast constraints in two places.  It is not valid to 
bitcast from one aggregate to another.

-  <dd>Convert a constant, CST, to another TYPE. The size of CST and TYPE must be
-  identical (same number of bits). The conversion is done as if the CST value
-  was stored to memory and read back as TYPE. In other words, no bits change 
-  with this operator, just the type.  This can be used for conversion of
-  aggregate types to any aggregate type, as long as they have the same bit
-  width. Vector types may also be casted to and from any other type as long as
-  they have the same bit width. For pointers it is only valid to cast to
-  another pointer type.
