difference in purpose of TargetInstrInfo and TargetInstrDesc,
which isn't immediately obvious from the name.

the BB member to the current basic block after emitting
instructions.

1e3fe05638 It is pointless to turn a UINT_TO_FP into an 
SINT_TO_FP libcall plus additional operations:
it might as well be a direct UINT_TO_FP libcall.
So only turn it into an SINT_TO_FP if the target
has special handling for SINT_TO_FP.

83d9009473 Add a SubclassData field to SDNode, similar to what's done 
in Value, to make use of some otherwise unused space. Use this
field to shrink LoadSDNode and StoreSDNode by moving the
addressing mode and ext/trunc fields there.

a6c09579f0 Add support for 128 bit multiplicative operations. 
Lack of these caused a bootstrap failure with Fortran
on x86-64 with LegalizeTypes turned on.  While there,
be nice to 16 bit machines and support expansion of
i32 too.

3ec3113431 - Change the horrible N^2 isRegReDefinedByTwoAddr. Now callers must supply the operand index of def machineoperand and at most one full scan of non-implicit operands is needed. 
- Change local register allocator to use the new isRegReDefinedByTwoAddr instead of reinventing the wheel.

80f6966c7f - Replace use of std::map<std::string, ..> with StringMap. Replace use of std::map with DenseMap, std::set with SmallPtrSet. This results in minor speed up. 
- Some code clean up.

e10fc737ca Simplify hasNUsesOfValue and hasAnyUsesOfValue even more. This 
makes their special-case checks of use_size() less beneficial,
so remove them. This eliminates all but one use of use_size(),
which is in AssignTopologicalOrder, which uses it only once for
each node, and so can reasonably afford to recompute it, as
this allows the UsesSize field of SDNode to be removed
altogether.

679872b05f Move MemoryVT out of LSBaseNode into MemSDNode, allowing the 
getMemOperand function to be moved into the base class as well
and made non-virtual.

f6e651fcf2 Move the IsVolatile and SVOffset fields into the MemSDNode base 
class, and store IsVolatile and Alignment in a more compact form.
This makes AtomicSDNode slightly larger, but it shrinks LoadSDNode
and StoreSDNode, which are much more common and are the largest of
the SDNode subclasses. Also, this lets the isVolatile() and
getAlignment() accessors be non-virtual.
