Johnny Chen d82f9002e4 Add NVCVTFrm (NEON Convert with fractional bits immediate) and modify N2VImm to
expect a Format arg.  N2VCvtD/N2VCvtQ are modified to use the NVCVTFrm format.

Johnny Chen 45ab3f3ccf Added a new instruction class NVDupLane to be inherited by VDUPLND and VDUPLNQ,
instead of the current N2V.  Format of NVDupLane instances are set to NEONFrm
currently.

Preliminary testing shows significant performance wins by not using these
instructions.

Johnny Chen e99953ce9c Reverted r99326 which added NVdVmVCVTFrm, and later renamed to NVCVTFrm.
NVCVTFrm will later be used to describe "vcvt with fractional bits".

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.

Bob Wilson 614d1fdfc3 Fix a very bad typo. Since the register number was off by one, the ARM
load/store optimizer would incorrectly think that registers D26 and D28
were consecutive and would generate a VLDM instruction to load them.
The assembler was not convinced.
