78a403f90e Remove the isTwoAddress property from the CodeGenInstruction class. It should
not be used for anything other than backwards compat constraint handling.

Add support for a new DisableEncoding property which contains a list of
registers that should not be encoded by the generated code emitter.  Convert
the codeemitter generator to use this, fixing some PPC JIT regressions.

4b0623e141 * Remove instruction fields hasInFlag / hasOutFlag and added SNDPInFlag and
SNDPOutFlag to DAG nodes. These properties do not belong to target specific
instructions.
* Added DAG node property SNDPOptInFlag. It's same as SNDPInFlag except it's
optional. Used by ret / call, etc.

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.

9b9567bfb5 Added support for ComplexPattern. These are patterns that require C++ pattern
matching code that is not currently auto-generated by tblgen, e.g. X86
addressing mode. Selection routines for complex patterns can return multiple operands, e.g. X86 addressing mode returns 4.

f02bb9af8b * 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.
