instructions.  Instead, keep a map of instructions -> MCFI objects in the
already sparc-specific class MachineFunctionInfo.  This will slow down the
sparc backend a bit, but it does not penalize the rest of LLVM!

Made a fix so that you can print out MachineInstrs that belong to a MachineBasicBlock that is not yet attached to a MachineFunction. This change includes changing the third operand (TargetMachine) to a pointer for the MachineInstr::print function.

The vector may actually be empty if the register that we are marking as
recently used is not actually allocatable.  This happens for physical registers
that are not allocatable, like the ST(x) registers on X86.

on X86.

broke obsequi and a lot of other things.  It all boiled down to MBB being
overloaded in an inner scope and me confusing it with the one in the outer
scope.  Ugh!

MBBs start out as #-1. When a MBB is added to a MachineFunction, it
gets the next available unique MBB number. If it is removed from a
MachineFunction, it goes back to being #-1.
