Johnny Chen 5dbf39285d Add New NEON Format NVdVmVCVTFrm. 
Converted some of the NEON vcvt instructions to this format.

Evan Cheng b6dee6e015 Teach isSafeToClobberEFLAGS to ignore dbg_value's. We need a MachineBasicBlock::iterator that does this automatically?

Bob Wilson 59f75bba24 Fix VLDMQ and VSTMQ instructions to use the correct encoding and address modes. 
These instructions are only needed for codegen, so I've removed all the
explicit encoding bits for now; they should be set in the same way as the for
VLDMD and VSTMD whenever we add encodings for VFP.  The use of addrmode5
requires that the instructions be custom-selected so that the number of
registers can be set in the AM5Opc value.

Daniel Dunbar de04b3f62c MC: Switch to using MCInst fragments to do relaxation. 
Also, both MCMachOStreamer and MCAssembler are now target independent!

Daniel Dunbar 16cbe95dd6 MC: Tweak MCInstFragment to include the encoded data and fixups, so that we don't need to recompute them during relaxation. I will revisit this once all the other pieces of fast relaxation are in place.

Devang Patel 53e91f0836 DW_AT_stmt_list attribute attached with a compile unit encodes offset of line number information for this compile unit in debug_line section. This offset is always zero when only one compile unit is emitted in a object file.

for the verifier.
