Bob Wilson 318ce7cb3f Fix the encoding of VLD4-dup alignment. 
The only reasonable way I could find to do this is to provide an alternate
version of the addrmode6 operand with a different encoding function.  Use it
for all the VLD-dup instructions for the sake of consistency.

Bob Wilson 0b27b68164 Rename VLDnDUP instructions with double-spaced registers 
in an attempt to make things a little more consistent.

The encoding for alignment in VLD4-dup instructions is still a work in progress.

Bob Wilson 04b2c94205 Another minor refactoring for VLD1DUP instructions. 
The op11_8 field is the same for all of them so put it in the instruction
classes instead of specifying it separately for each instruction.

Jim Grosbach a74c7ccd59 ARM PseudoInst instructions don't need or use an assembler string. Get rid of 
the operand to the pattern.

Bill Wendling a68e3a5397 Encode the multi-load/store instructions with their respective modes ('ia', 
'db', 'ib', 'da') instead of having that mode as a separate field in the
instruction. It's more convenient for the asm parser and much more readable for
humans.

Owen Anderson 0747307049 Add support for code generation of the one register with immediate form of vorr. 
We could be more aggressive about making this work for a larger range of constants,
but this seems like a good start.

Owen Anderson bb81f80af6 Unlike a lot of NEON instructions, vext isn't _actually_ parameterized by element size. Instead, 
all of the different element sizes are pseudo instructions that map down to vext.8 underneath, with
the immediate shifted left to reflect the increased element size.
