the index when the value evaluation isn't powerful enough.  By creating ElementRegions with
UnknownVals as the index, this gives the false impression that they are the same element, when
they really aren't.  This becomes really problematic when deriving symbols from these regions
(e.g., those representing the initial value of the index), since two different indices will
get the same symbol for their binding.

This fixes an issue with the idempotent operations checker that would cause two indices that
are clearly not the same to make it appear as if they always had the same value.

Fixes <rdar://problem/8431728>.

Don't divide-by-zero in RegionStoreManager::getSizeInElements() when getting the size of a VLA.  We don't track VLA extents yet,

Handle %test_debuginfo on a RUN command line.

This set up now allows one to write small test cases to check debug info.
e.g.

; RUN: %clang -O0 -g %s -c -o %t.o
; RUN: %clang %t.o -o %t.out  
; RUN: %test_debuginfo %s %t.out

define i32 @f1(i32 %i) nounwind ssp {
; DEBUGGER: break f1                                                               
; DEBUGGER: r                                                                      
; DEBUGGER: p i                                                                    
; CHECK: $1 = 42

  %i.addr = alloca i32, align 4

}

It is also possible now to write test cases in c/c++.
The plan is to store these debug info testcases in a separate place.
