The immediate is of limited range and the operand type should reflect that.

Update the debug output interface for MCParsedAsmOperand to have a print()
method which takes an output stream argument, an << operator which invokes
the print method using the given stream, and a dump() method which prints
the operand to the dbgs() stream. This makes the interface more consistent
with the rest of LLVM, and more convenient to use at the debugger command
line.

if (x != 0) x = 1
if (x == 1) x = 1

Previous codegen looks like this:
        mov     r1, r0
        cmp     r1, #1
        mov     r0, #0
        moveq   r0, #1

The naive lowering select between two different values. It should recognize the
test is equality test so it's more a conditional move rather than a select:
        cmp     r0, #1
        movne   r0, #0

LinearFunctionTestReplace rewrite. No functionality.

I've been wanting to group the indvar subphases into sections and
order them by their logical sequence. My next checkin adds functions
related to LFTR, and doing the reorg now should help reviewers. Since,
most of the code in IndVarSimplify.cpp has recently been replaced or
will be replaced soon, obscuring blame should not be an issue. This
seems like an ideal time to shuffle the code around.

I'm happy to take more suggestions for cleaning up the code. Or if
you've been wanting to cleanup anything in this file yourself, now is
a good time.

The enum names as well as order (i.e. value)
had skewed, which means that consumers of the
tablegen-ed table would see different values than
intended. Make both files have a superset of enums,
and add classification as needed for numMCOperands.

Print shifted immediate values directly rather than as a payload+shifter
value pair. This makes for more readable output assembly code, simplifies
the instruction printer, and is consistent with how Thumb immediates are
 displayed.

- Added methods to update subtarget features (used when targets automatically
  detect subtarget features or switch modes).
- Teach X86Subtarget to update MCSubtargetInfo features bits since the
  MCSubtargetInfo layer can be shared with other modules.
- These fixes .code 16 / .code 32 support since mode switch is updated in
  MCSubtargetInfo so MC code emitter can do the right thing.
