definitions. This adds a new construct, "discard", for indicating
that a named node in the input matching pattern is to be discarded,
instead of corresponding to a node in the output pattern. This
allows tblgen to know where the arguments for the varaible_ops are
supposed to begin.

This fixes "rdar://5791600", whatever that is ;-).

instruction to execute. This can be used for transformations (like two-address
conversion) to remat an instruction instead of generating a "move"
instruction. The idea is to decrease the live ranges and register pressure and
all that jazz.

instructions and constant expressions.

Note that this does not yet include CodeGen support.

DAG instruction selectors. Introudce a dedicated header file for this part:
include/llvm/CodeGen/DAGISelHeader.h

TableGen now only generates the include preprocessor directive to include this
new header.

This is a preparation for supporting multiple implementations of instruction
selectors in the future.

Makes it possible to use options with names like "Wa,".
Also fixes the -Wall option handling as a side-effect.

VisualStudio project files updated.  #include <algorithm> added to make VisualStudio happy.  Also had to undefine setjmp because of #include <csetjmp> turning setjmp into _setjmp in VisualStudio.

Sort sub-registers and super-registers lists according to super-sub register relations. e.g. X86::RAX sub-register list is EAX, AX, AL, AH (order of last two are not guaranteed).

string began at a power of 2 in the string index.  For example, if "ret" started
at position 16, the ret instruction would be assigned code 16, but the mask would be AsmChars[] + Code & 15, not Code & 31.
