5e84368b26 Reapply 53476 and 53480, with a fix so that it properly updates 
the BB member to the current basic block after emitting
instructions.

ac6cecec18 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.

addressing mode and ext/trunc fields there.

5ac319ac71 Add support for 128 bit multiplicative operations.

i32 too.

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.

250c1d8734 - 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.

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.

1ea58a52a4 Move MemoryVT out of LSBaseNode into MemSDNode, allowing the

and made non-virtual.

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.
