the "identifier" parsed by the frontend callback by skipping forward
until we've consumed a token that ends at the point dictated by the
callback.

In addition, inform the callback when it's parsing an unevaluated
operand (e.g. mov eax, LENGTH A::x) as opposed to an evaluated one
(e.g. mov eax, [A::x]).

- Define pseudo instructions which store or load ccond field of the DSP
  control register.
- Emit the pseudos in MipsSEInstrInfo::storeRegToStack and loadRegFromStack.
- Expand the pseudos before callee-scan save.
- Emit instructions RDDSP or WRDSP to copy between ccond field and GPRs.

Actually it took me couple of hours trying to make sense of them and
only to find they are dead code.  I guess the original author used
"allSingleSucc" to indicate if there are any critial edge emanating
from some blocks, and tried to perform code motion (actually speculation)
in the presence of these critical edges; but later on he/she changed mind
and decided to perform edge-splitting first.

  * lib/Target/Hexagon/HexagonInstrInfo.cpp (GetDotNewPredOp):
  Given a jump opcode return the right pred.new jump opcode with
  a taken vs not-taken hint based on branch probabilities provided
  by the target independent module.
  * lib/Target/Hexagon/HexagonVLIWPacketizer.cpp: Use the above function.
  * lib/Target/Hexagon/HexagonNewValueJump.cpp(getNewvalueJumpOpcode):
  Enhance existing function use branch probabilities like
  HexagonInstrInfo::GetDotNewPredOp but for New Value (GPR) Jumps.

All but two patterns have been converted to the new syntax.  The
remaining two patterns will require COPY_TO_REGCLASS instructions, which
the VLIW DAG Scheduler cannot handle.

Fortunately this pattern never matched, otherwise
we would have generated incorrect code.

at all of the operands. Previously it was skipping over implicit operands which
cause infinite looping when the two-address pass try to reschedule a
two-address instruction below the kill of tied operand.

I'm unable to come up with a reasonably sized test case.

CodeModel: It's now possible to create an MCJIT instance with any CodeModel you like.  Previously it was only possible to 
create an MCJIT that used CodeModel::JITDefault.

EnableFastISel: It's now possible to turn on the fast instruction selector.

The CodeModel option required some trickery.  The problem is that previously, we were ensuring future binary compatibility in 
the MCJITCompilerOptions by mandating that the user bzero's the options struct and passes the sizeof() that he saw; the 
bindings then bzero the remaining bits.  This works great but assumes that the bitwise zero equivalent of any field is a 
sensible default value.

But this is not the case for LLVMCodeModel, or its internal equivalent, llvm::CodeModel::Model.  In both of those, the default 
for a JIT is CodeModel::JITDefault (or LLVMCodeModelJITDefault), which is not bitwise zero.

Hence this change introduces LLVMInitializeMCJITCompilerOptions(), which will initialize the user's options struct with
defaults. The user will use this in the same way that they would have previously used memset() or bzero(). MCJITCAPITest.cpp
illustrates the change, as does the comment in ExecutionEngine.h.

The old jit always uses DW_EH_PE_absptr, but MCJIT can use other encodings.
This is in preparation for adding EH support to MCJIT, but not directly
related, so I am committing it first.

the things, and renames it to CBindingWrapping.h.  I also moved 
CBindingWrapping.h into Support/.

This new file just contains the macros for defining different wrap/unwrap 
methods.

The calls to those macros, as well as any custom wrap/unwrap definitions 
(like for array of Values for example), are put into corresponding C++ 
headers.

Doing this required some #include surgery, since some .cpp files relied 
on the fact that including Wrap.h implicitly caused the inclusion of a 
bunch of other things.

This also now means that the C++ headers will include their corresponding 
C API headers; for example Value.h must include llvm-c/Core.h.  I think 
this is harmless, since the C API headers contain just external function 
declarations and some C types, so I don't believe there should be any 
nasty dependency issues here.
