6627a32ff9 Merging the linear scan register allocator in trunk. It currently passes most tests under test/Programs/SingleSource/Benchmarks/Shootout so development will continue on trunk. The allocator is not enabled by default. You will need to pass -regallo=linearscan to lli or llc to use it.

612254327c Fix problems linking against the reoptimizer; _llvm_regAllocState must have
externally-visible linkage, and SaveStateToModule must default to true for llc.
I don't remember why I made it const; perhaps it should be deconstified.

490bf81152 Operand numbers are now ints. Save the register allocation of the value
each instruction produces as "operand" -1, and the other operands as 0
.. n, as before. PhyRegAlloc::saveState() is refactored into
PhyRegAlloc::saveStateForValue().

8dadbe31dc Update verifySavedState()'s comment, so that it reflects its current
status.  In doFinalization(), skip over external functions, just like
Anand's mapping info does.

29d56dd004 Include llvm/CodeGen/MachineCodeForInstruction.h. Use it to start
implementing verifySavedState().

In saveState(), use the new AllocInfo::AllocStateTy enum, and increment
Insn each time through the loop.

04e6824a3f Publicize the type of FnAllocState.
Prototype option to save state in a global instead of as a Constant in
 the Module. (Turned off, for now, with the on/off switch welded in the off
 position. You get the idea.)

 AllocInfos to LLVM Constants.

5952eddbfb Don't worry about converting each function's reg. alloc. state into One Big

74568bc9d4 Change MRegisterDesc::AliasSet, TargetInstrDescriptor::ImplicitDefs
and TargetInstrDescriptor::ImplicitUses to always point to a null
terminated array and never be null. So there is no need to check for
pointer validity when iterating over those sets. Code that looked
like:

if (const unsigned* AS = TID.ImplicitDefs) {
  for (int i = 0; AS[i]; ++i) {
    // use AS[i]
  }
}

was changed to:

for (const unsigned* AS = TID.ImplicitDefs; *AS; ++AS) {
  // use *AS
}
