Unbreak name/hashcode/equal for float/fixnum/etc. tmp vars

* Closure, float, boolean, fixnum were all using "%v_" prefixes.

* Some code refactoring somewhere broke this.

* Since closure and non-clusre tmp vars aren't used in the same
  scope, this doesn't cause hashing conflicts. But, with unboxing,
  this bug got exposed since these types co-exist within the same
  scope.

* IR output now also use the "%cl_1_5" form for local variables in
  closures which makes for easier debugging.

* Also used a base equals implementation in TemporaryVariable
  which mirrors the hashCode() implementation there.
