62aa905595 The 64-bit constructor for ConstantInt changes from int64_t to uint64_t.
This caused a warning for construction with -1. Avoid the warning by using
-1ULL instead.

a6e8a955d6 Remove the "isSigned" parameters from ConstantRange. It turns out they
are not needed as the results are the same with or without it.

only APInt and not use ConstantInt. Clients are adjusted accordingly.

832254e1c2 Changes to support making the shift instructions be true BinaryOperators.
This feature is needed in order to support shifts of more than 255 bits
on large integer types.  This changes the syntax for llvm assembly to
make shl, ashr and lshr instructions look like a binary operator:
   shl i32 %X, 1
instead of
   shl i32 %X, i8 1
Additionally, this should help a few passes perform additional optimizations.

c5eff4488b Symbolically evaluate constant expressions like &A[123] - &A[4].f.
This occurs in C++ code like:

#include <iostream>
#include <iterator>
int a[] = { 1, 2, 3, 4, 5 };
int main() {
  using namespace std;
  copy(a, a + sizeof(a)/sizeof(a[0]), ostream_iterator<int>(cout, "\n"));
  return 0;
}

Before we would decide the loop trip count is:
sdiv (i32 sub (i32 ptrtoint (i32* getelementptr ([5 x i32]* @a, i32 0, i32 5) to i32), i32 ptrtoint ([5 x i32]* @a to i32)), i32 4)

Now we decide it is "5".  Amazing.

This code will need to be refactored, but I'm doing that as a separate
commit.
