machine instruction is generated (e.g., Cast).
Other changes due to changes to classes TargetMachine and MachineInstr.

Added MachineInstrInfo class and moved instruction-related members there.
Added several fields to MachineInstrDescriptor (and renamed it from
MachineInstrInfo.  Latency fields are to support scheduling.

Eliminate separate enum for operand register type.
Use union for alternative data for different operand types.
Add iterator over Value* operands in a MachineInstr.

Work around a few 'sorting issues' with the bytecode output that causes the bytecode
not to be bit for bit identical.  This is a hack and should be fixed in the future

Don't write out constants that do not have a name, they will be inlined.

Refactor some of the constant stuff so that we can return complex constant
values directly.  This was causing test failures. :(

Add an arg to insertVal to allow us to prevent builtin types from being ignored
when they are inserted.

Ignore constant values without names.  If they are used, they will be inlined.
