c298c8ed4d Make Thumb2 LEA-like instruction into pseudos, which map down to ADR. Provide correct fixups for Thumb2 ADR, 
which is _of course_ different from ARM ADR fixups, or any other Thumb2 fixup.

4ec912b842 In Thumb2, direct branches can be encoded as either a "short" conditional branch with a null predicate, or 
as a "long" direct branch.  While the mnemonics are the same, they encode the branch offset differently, and
the Darwin assembler appears to prefer the "long" form for direct branches.  Thus, in the name of bitwise
equivalence, provide encoding and fixup support for it.

16e7d7bf2f Add support for using the `!if' operator when initializing variables: 
class A<bit a, bits<3> x, bits<3> y> {
    bits<3> z;
    let z = !if(a, x, y);
  }

The variable z will get the value of x when 'a' is 1 and 'y' when a is '0'.

bd5b0c9ec6 Add a license comment to the generated arm_neon.h header. 
Remove the previous header.  I don't think we need to expose to end users
that we use TableGen to produce our version of arm_neon.h, and that header
was also using doubleslash comments which could be a problem when using it
in strict C89 compilations.

cd8fdfd65f The BLX instruction is encoded differently than the BL, because why not? In 
particular, the immediate has 20-bits of value instead of 21. And bit 0 is '0'
always. Going through the BL fixup encoding was trashing the "bit 0 is '0'"
invariant.

Attempt to get the encoding at slightly more correct with this.

f909f96f2b Add an OpReinterpret operation to TableGen's NeonEmitter. 
An OpReinterpret entry is handled by translating it to OpCast intrinsics for
all combinations of source and destination types with the same total size.
This will be used to generate all the vreinterpret intrinsics.
