8d3d8c5788 Split JMPL into JMPLCALL and JMPLRET so that IsCall and IsReturn can 
be used to distinguish those uses of the `jmpl' instruction.

3495dd8b2f Fix bug exposed by this testcase: 
declare int "call_operand"      (%rtx_def*, int)        ;; Prototype for: call_operand
declare int "restore_operand"   (%rtx_def*, int)        ;; Prototype for: restore_operand

%rtx_def = type opaque
%rtx_def = type int

8acdb272f4 Two changes: 
1. Delete type handle regardless of whether a collision occured
2. Remove a MAJOR pessimization of runtime performance (thought be be an optimization at the time).

This second one was causing a 105k llvm file (from gcc) to parse in 58 seconds... without the
'optimization' it now parses in 3.64 seconds.  I suck.
