a3b5b71616 For PR1205: 
Implement review feedback:
1. Use new APInt::RoundDoubleToAPInt interface to specify the bit width so
   that we don't have to truncate or extend in constant folding.
2. Fix a pasteo in SDiv that prevented a check for overflow.
3. Fix the shift operators: undef happens when the shift amount is equal
   to the bitwidth.

c8cc0f997e For PR1205: 
Implement the first step towards arbitrary precision integer support in
LLVM. The APInt class provides arbitrary precision arithmetic and value
representation. This patch changes ConstantInt to use APInt as its value
representation without supporting bit widths > 64 yet. That change will
come after ConstantFolding handles bit widths > 64 bits.

50be7cd320 Rework GlobalValue::removeDeadConstantUsers to always remove dead constant 
exprs hanging off a global, even if the global is not otherwise dead.  This
requires some tricky iterator gymnastics.

This implements Transforms/GlobalOpt/constantexpr-dangle.ll by deleting a
constantexpr that made it appear that the address of the function was taken.

37a49eb48d cleanup ConstantInt to use a single DenseMap for uniquing instead of the 
heavy-weight ValueMap class.  This reduces mem usage bc reading kc++ by 29K,
even though it only creates 2955 constant ints!

9084bb5471 rewrite Value::takeName to take advantage of the new symtab stuff. This 
causes it to require no allocations and no symtab lookups in the common
case.  This speeds up instcombine 9.2% on 447.dealII.

5a58a65c10 Switch ValueSymbolTable to use StringMap<Value*> instead of std::map<std::string, Value*>
