on 16 bit machines.

c563e1d8fe Fix a bug in the soft-float handling of FCOPYSIGN that Duncan noticed 
when working on legalizetypes.  Both legalizetypes and legalizeops now
produce hte same code for CodeGen/ARM/fcopysign.ll.

5ac319ac71 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.

expansion for these.

ef0732d25a - 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.

b9c33c3229 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.

and made non-virtual.

eb580ee133 Loosen our check here. Local regalloc only cares that the reg is used and def'd by the same instruction, but about the details of 
the relationship.

492f276cbc 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.

dd4b47c9b2 Don't use an expensive check for two-address-ness when we have the information sitting around to determine it much more quickly, 
This speeds up the local register allocator from 0.37s to 0.31s on instcombine.
