Eric Christopher 7258dcd77f Revert 101465, it broke internal OpenGL testing. 
Probably the best way to know that all getOperand() calls have been handled
is to replace that API instead of updating.

Gabor Greif f375520f7b reapply r101434 
with a fix for self-hosting

rotate CallInst operands, i.e. move callee to the back
of the operand array

the motivation for this patch are laid out in my mail to llvm-commits:
more efficient access to operands and callee, faster callgraph-construction,
smaller compiler binary

Duncan Sands 19d0b47b1f There are two ways of checking for a given type, for example isa<PointerType>(T) 
and T->isPointerTy().  Convert most instances of the first form to the second form.
Requested by Chris.

Duncan Sands 9dff9bec31 Uniformize the names of type predicates: rather than having isFloatTy and 
isInteger, we now have isFloatTy and isIntegerTy.  Requested by Chris!

Dan Gohman 28943873e6 Use do+while instead of while for loops which obviously have a 
non-zero trip count. Use SmallVector's pop_back_val().

Chris Lattner 0a8191ee88 split and/or/xor out into one overly-large (2000LOC) file. However, I think 
it does make sense to keep them together, at least for now.

Chris Lattner 9da1cb243b optimize cttz and ctlz when we can prove something about the 
leading/trailing bits.  Patch by Alastair Lynn!

Chris Lattner 82aa888e8c split add/sub out to its own file. Eliminate use of 
dyn_castNotVal in the X+~X transform.  dyn_castNotVal is
dramatic overkill for what the xform needed.

Chris Lattner c7de92ae15 all the places we use hasOneUse() we know are instructions, so inline 
and simplify.

Chris Lattner 98d48a0b76 inline the 'AddRHS' transformation, simplifying things significantly. 
Eliminate the 'AddMaskingAnd' transformation, it is redundant with this
more general code right below it:
  // A+B --> A|B iff A and B have no bits set in common.

Chris Lattner 39b063bf37 remove massive over-genality manifested as a big template 
that got instantiated.  There is no reason for instcombine
to try this hard for simple associative optimizations.  Next
up, eliminate the template completely.

Devang Patel be94f23992 Remove dead debug info intrinsics. 
Intrinsic::dbg_stoppoint
 Intrinsic::dbg_region_start
