Change ConstantPoolSDNode to actually hold the Constant itself instead of
putting it into the constant pool. This allows the isel machinery to
create constants that it will end up deciding are not needed, without them
ending up in the resultant function constant pool.

add a new TargetFrameIndex node

Add 5-operand version of SelectNodeTo

ADd support for TargetGlobalAddress nodes

Add support for target DAG nodes that take 4 operands, such as PowerPC's
rlwinm.

Add two new methods isTargetOpcode() which returns true if the node type
is greater than the range of building selection dag node types, and
getTargetOpcode(), which returns the node opcode less the value of
isd::builtin_op_end, which specifies the end of the builtin types.

Move the code dependency for MathExtras.h from SelectionDAGNodes.h.

Added some class dividers in SelectionDAG.cpp.

Culling out use of unions for converting FP to bits and vice versa.

Make removeUser more efficient, add a matching addUser.
Fix the setOperands methods I added to update use/def information correctly.

llvm-svn: 22832

make sure to remove a node from the use list of its operands when we replace
it.

llvm-svn: 22820

add some helper methods, and a new TargetConstant node, which is not
subjected to folding.

Eliminate the RegSDNode class, which 3 nodes (CopyFromReg/CopyToReg/ImplicitDef)
used to tack a register number onto the node.

Instead of doing this, make a new node, RegisterSDNode, which is a leaf
containing a register number. These three operations just become normal
DAG nodes now, instead of requiring special handling.

Note that with this change, it is no longer correct to make illegal
CopyFromReg/CopyToReg nodes. The legalizer will not touch them, and this
is bad, so don't do it. :)

Implement BR_CC and BRTWOWAY_CC. This allows the removal of a rather nasty
fixme from the PowerPC backend. Emit slightly better code for legalizing
select_cc.

allow passing a dag into getOperationName and dump

add some methods for dag->dag isel

Add new node, SELECT_CC. This node is for targets that don't natively
implement SELECT.

Change *EXTLOAD to use an VTSDNode operand instead of being an MVTSDNode.
This is the last MVTSDNode.

This allows us to eliminate a bunch of special case code for handling
MVTSDNodes.

Introduce a new VTSDNode class with the ultimate goal of eliminating the
MVTSDNode class. This class is used to provide an operand to operators
that require an extra type. We start by converting FP_ROUND_INREG and
SIGN_EXTEND_INREG over to using it.
