bbcf30c05c Pass the optimization level when constructing the ARM instruction selector.
Otherwise, it is always set to "default", which prevents debug info from
even being generated during isel.  Radar 7250345.

55df534293 Change TargetAsmInfo to be constructed via TargetRegistry from a Target+Triple
pair instead of from a virtual method on TargetMachine.  This cuts the final
ties of TargetAsmInfo to TargetMachine, meaning that MC can now use 
TargetAsmInfo.

6ee52e0047 Add a new pre-allocation pass to assign adjacent registers for Neon instructions
that have that constraint.  This is currently just assigning a fixed set of
registers, and it only handles VLDn for n=2,3,4 with DPR registers.
I'm going to expand it to handle more operations next; we can make it smarter
once everything is working correctly.

1fe51064ba Change DAG nodes for Neon VLD2/3/4 operations to return multiple results.
Get rid of yesterday's code to fix the register usage during isel.
Select the new DAG nodes to machine instructions.  The new pre-alloc pass
to choose adjacent registers for these results is not done, so the
results of this will generally not assemble yet.

0b82c938fe Normalize Subtarget constructors to take a target triple string instead of
Module*.

Also, dropped uses of TargetMachine where unnecessary. The only target which
still takes a TargetMachine& is Mips, I would appreciate it if someone would
normalize this to match other targets.

23bba6d075 Replace large swaths of copy-n-paste code with obvious helper function...
- Which was already present in the module!

 - I skipped this xform for Alpha, since it runs an extra pass during assembly
   emission, but not when emitting assembly via the DumpAsm flag.

 - No functionality change.

d0a66e438f Add a ARM specific pre-allocation pass that re-schedule loads / stores from
consecutive addresses togther. This makes it easier for the post-allocation pass
to form ldm / stm.

This is step 1. We are still missing a lot of ldm / stm opportunities because
of register allocation are not done in the desired order. More enhancements
coming.
