14496ddfd4 Do not dereference invalid ranges. Generalize targetdata alignment model. 
This fixes the UnitTests/Vector/sumarray-dbl regressions.

d22266f456 Review changes: 
1. Function style changes.
2. 80-col violations.
3. Better names for things.
4. Arrange constructors so they all take bit width first.
5. Add named signed and unsigned comparison functions and remove the
   corresponding operators.
6. Remove operator&& and operator|| but provide a getBoolValue function which
   converts to bool as comparison against 0. This allows the normal && and
   || operators to be used as if (X.getBoolValue() && Y.getBoolValue())

Note: this still doesn't function 100% yet. I'm working on the bugs now.

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.

fc2686da00 From Dan Gohman: 
While preparing http://llvm.org/PR1198 I noticed several asserts
protecting unprepared code from i128 types that weren't actually failing
when they should because they were written as assert("foo") instead of
something like assert(0 && "foo"). This patch fixes all the cases that a
quick grep found.

80ac48cfdf Make some minor improvements to APInt:

2. Rename APIntRoundToDouble method just RoundToDouble, the APInt is
   redundant.
3. Turn the class on for compilation.
