I should be able to cleanup one backend at a time.

The comment about ordering of subreg indices is no longer true.
This exposed a bug in the new substVirtReg method that is also fixed.

that are too large.  This causes the freebsd bootloader to be too
large apparently.

It's unclear if this should be an -Os or -Oz thing.  Thoughts welcome.

doesn't needs its EnableFastISel argument.

implementation that is correct for most targets. Tablegen will override where
needed.

Add MachineOperand::subst{Virt,Phys}Reg methods that correctly handle existing
subreg indices when sustituting registers.

This will help reduce the amount of casting required on 64-bit targets.

optimization level.

This only really affects llc for now because both the llvm-gcc and clang front
ends override the default register allocator. I intend to remove that code later.

inlined function's arguments need a label to mark the start point because they are not directly attached to current function.

There is no need to force an line number entry (using previous location) for a temp label at unknown location.
