'insertvalue' instructions that recreate the structure returned by the
'landingpad' instruction. Because the 'insertvalue' instruction isn't supported
by FastISel, this can save a bit of time during -O0 compilation.

Add a new form of MCOperand, for representing sub-instructions.  This is intended for supporting bundles through the MC layer, rather than lowering them pre-MC as we currently do for Thumb2 IT blocks.  Since these sub-instruction operands hold pointers to the sub-instructions, it is the responsibility of the target's AsmPrinter to provide storage for them for the duration of the EmitInstruction() call.

  to instruction right after the last instruction in the bundle.
- Add a finalizeBundle() variant that doesn't specify LastMI. Instead, the code
  will find the last instruction in the bundle by following the 'InsideBundle'
  marker. This is useful in case bundles are formed early (i.e. during MI
  scheduling) but finalized later (i.e. after register allocator has finished
  rewriting virtual registers with physical registers).

It adds register mask operands to x86 call instructions.  Once all the
backend passes support register mask operands, this will be permanently
enabled.

This is similar to implicit register operands.  MC doesn't understand
register liveness and call clobbers.

This SelectionDAG node will be attached to call nodes by LowerCall(),
and eventually becomes a MO_RegisterMask MachineOperand on the
MachineInstr representing the call instruction.

LowerCall() will attach a register mask that depends on the calling
convention.

If the two fragments are in the same Atom, then the difference
expression is resolvable at compile time. Previously we were checking
that they were in the same fragment, but that breaks down in the
presence of instruction relaxation which has multiple fragments in the
same atom.
