28977af72a 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.

be883a23ed Do not use index type to determine what it is indexing into!

8fce16ef1a 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

fe7ea0da17 Minor optimization efficiency improvement: 
- Run mem2reg promotion first
  - Only rerun passes if the previous thing changed something

whether the constant is signed or unsigned, then casting

b37923f9a1 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.

behavior is technically undefined
