5bdef4b3f7 Checkpoint Thumb2 Instr info work. Generalized base code so that it can be shared between ARM and Thumb2. Not yet activated because register information must be generalized first.

e176389cc7 Mark sublw_cc and subfw_cc as Terminator insns so that they are part of the terminator insns for a basic block alongwith branch insns. This way a copy is not getting inserted between cmp and branch during PHIElimination disturbing the status flags.

ea7bd9b484 dag combine sext(setcc) -> vsetcc before legalize. To make this safe, 
VSETCC must define all bits, which is different than it was documented
to before.  Since all targets that implement VSETCC already have this
behavior, and we don't optimize based on this, just change the 
documentation.  We now get nice code for vec_compare.ll

f77b78ed70 Operand of asm("call") (the callee function) is represented 
as "X" constraint and "P" modifier on x86.  Make this work.
(Change may not be sufficient to fix it for non-Darwin, but
I'm pretty sure it won't break anything.)

20158261a7 DWARF requires frame moves be specified at specific times. If you have a 
prologue like this:

__Z3fooi:
Leh_func_begin1:
LBB1_0: ## entry
        pushl   %ebp
Llabel1:
        movl    %esp, %ebp
Llabel2:
        pushl   %esi
Llabel3:
        subl    $20, %esp
        call    "L1$pb"
"L1$pb":
        popl    %esi

The "pushl %ebp" needs a table entry specifying the offset. The "movl %esp,
%ebp" makes %ebp the new stack frame register, so that needs to be specified in
DWARF. And "pushl %esi" saves the callee-saved %esi register, which also needs
to be specified in DWARF.

Before, all of this logic was in one method. This didn't work too well, because
as you can see there are multiple FDE line entries that need to be created.

This fix creates the "MachineMove" objects directly when they're needed; instead
of waiting until the end, and losing information.

2bbbcbca79 fix some type confusion in ReadVBR64: "Piece" should be only 32 bits, 
not 64, because we read at most 32 bits at a time.  OTOH, "Result" must
be 64-bits and insertion into it must be 64-bit clean.  Thanks to Ivan
Sorokin for bringing this up.
