refactor x86-64 argument lowering yet again, this time eliminating templates,
'clients', etc, and adding CCValAssign instead.

Backing out Jim's LR spill changes. This was causing llvm-gcc bootstrapping

PPCMachineFunctionInfo.h updated: 1.2 -> 1.3
PPCRegisterInfo.cpp updated: 1.110 -> 1.111
PPCRegisterInfo.h updated: 1.28 -> 1.29

Simplify and document RoundDoubleToAPInt.

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.

1. Make sure all delete operators of arrays use the array form of delete.
2. Rewrite operator=(const APInt& RHS) to allow the RHS to be a different
   bit width than the LHS. This makes it possible to use APInt as the key
   of a DenseMap, as needed for the IntConstants map in Constants.cpp
3. Fix operator=(uint64_t) to clear unused bits in case the client assigns
   a value that has more bits than the APInt allows.
4. Assert that bit widths are equal in operator==
5. Revise getHashValue() to put the bit width in the low order six bits.
   This should help to make i1 0, i2 0, ... i64 0 all distinct in the
   IntConstants DenseMap.
