0b908c75a6 Only print values live at BB or method exit, and insert loads at each 
BB exit to read and print values stored in that BB.   Note that only
these stored values are live at method exit!.  Also, print messages at
method entry and exit.

487da75338 Handle multiple exit blocks correctly. 
Restore string variable cache.
Resurrect code to use formatted printing instead of PrintVal
but leave it turned off for now.

a8ed40026f Massive hacks to try to fix subtle logic bugs. I think it's all working now, 
at least what used to.  I should disable method exit code completely because
it's broken (doesn't insert just post dominating values)

c00392210d Broad superficial changes:

6f7587e4d3 Changed the fundemental architecture of Operands for Instructions. Now 
Operands are maintained as a vector<Use> in the User class, and operator
iterators are provided as before.  Getting an operand no longer requires
a virtual function call.

WARNING: getOperand(x) where x >= getNumOperands() will now assert instead
of returning null!
