Chris Lattner b5f8eb8315 Do not loop over uses as we delete them. This causes iterators to be 
invalidated out from under us.  This bug goes back to revision 1.1: scary.

Chris Lattner 69193f93b6 Support getelementptr instructions which use uint's to index into structure 
types and can have arbitrary 32- and 64-bit integer types indexing into
sequential types.

John Criswell 482202a601 Added LLVM project notice to the top of every C++ source file. 
Header files will be on the way.

Chris Lattner 7fdde92b1f Do not return success after checking only the FIRST USE of a gep instruction. 
Instead, check all uses.
This fixes bug: ScalarRepl/2003-09-12-IncorrectPromote.ll
This also fixes the miscompilation of Ptrdist/bc

Chris Lattner 9a95f2a944 Minor optimization efficiency improvement: 
- Run mem2reg promotion first
  - Only rerun passes if the previous thing changed something

Chris Lattner 5d8a12e094 Integrate functionality of the mem2reg pass directly into this pass to make 
the combination more effective

Chris Lattner 6077c3195f Simplify code by using ConstantInt::getRawValue instead of checking to see 
whether the constant is signed or unsigned, then casting

Chris Lattner 0078d9c5bb Okay totally give up on trying to optimize aggregates that cannot be completely 
broken up into their elements.  Too many programs break because of this.

Chris Lattner d847be0539 add a check that allows the SRoA pass to avoid breaking programs, even if their 
behavior is technically undefined
