Evan Cheng 7785e5b3a4 New DAG node properties SNDPInFlag, SNDPOutFlag, and SNDPOptInFlag to replace 
hasInFlag, hasOutFlag.

Evan Cheng 14c53b45f5 Added field noResults to Instruction. 
Currently tblgen cannot tell which operands in the operand list are results so
it assumes the first one is a result. This is bad. Ideally we would fix this
by separating results from inputs, e.g. (res R32:$dst),
(ops R32:$src1, R32:$src2). But that's a more distruptive change. Adding
'let noResults = 1' is the workaround to tell tblgen that the instruction does
not produces a result. It works for now since tblgen does not support
instructions which produce multiple results.

Evan Cheng 9ae486047e * Removed the use of FLAG. Now use hasFlagIn and hasFlagOut instead. 
* Added a pseudo instruction (for each target) that represent "return void".
  This is a workaround for lack of optional flag operand (return void is not
  lowered so it does not have a flag operand.)

Evan Cheng e8531381e2 * 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.

Nate Begeman 006bb04f3a Support multiple ValueTypes per RegisterClass, needed for upcoming vector 
work.  This change has no effect on generated code.

Nate Begeman 89b049af90 Add the majority of the vector machien value types we expect to support, 
and make a few changes to the legalization machinery to support more than
16 types.
