cf4f349880 * Commit the fix (by Chris) for a tblgen type inferencing bug. 
* Enhanced tblgen to handle instructions which have chain operand and writes a
chain result.
* Enhanced tblgen to handle instructions which produces no results. Part of
the change is a temporary hack which relies on instruction property (e.g.
isReturn, isBranch). The proper fix would be to change the .td syntax to
separate results dag from ops dag.

7580d9229f * Added instruction property hasCtrlDep for those which r/w control-flow 
chains.
* Added DAG node property SDNPHasChain for nodes which r/w control-flow
  chains.
* Renamed SDTVT to SDTOther.
* Added several new SDTypeProfiles for BR, BRCOND, RET, and WRITEPORT.
* Added SDNode definitions for BR, BRCOND, RET, and WRITEPORT.

1b8459d092 Fix test/Regression/ExecutionEngine/2005-12-02-TailCallBug.ll and PR672. 
This also fixes 177.mesa, the only program that fails with --enable-x86-fastcc
turned on.  Given a clean nightly tester run, we should be able to turn it
on by default!

282123f7fc This is a bugfix for SelectNodeTo. In certain situations, we could be 
selecting a node and use a mix of getTargetNode() and SelectNodeTo.  Because
SelectNodeTo didn't check the CSE maps for a preexisting node and didn't insert
its result into the CSE maps, we would sometimes miss a CSE opportunity.

This is extremely rare, but worth fixing for completeness.

9c3508e1ab Teach tblgen to accept register source operands in patterns, e.g. 
def SHL8rCL  : I<0xD2, MRM4r, (ops R8 :$dst, R8 :$src),
                 "shl{b} {%cl, $dst|$dst, %CL}",
                 [(set R8:$dst, (shl R8:$src, CL))]>, Imp<[CL],[]>;

This generates a CopyToReg operand and added its 2nd result to the shl as
a flag operand.

466eaefd38 Stop checking the ValueType of the CodeGenInstruction. Instead, use the 
ValueType from the RegisterClass or Operands.  This step is necessary to
allow RegisterClasses to have multiple ValueTypes.
