b0abb4dc42 Use vAny type to get rid of Neon intrinsics that differed only in whether
the overloaded vector types allowed floating-point or integer vector elements.
Most of these operations actually depend on the element type, so bitcasting
was not an option.

If you include the vpadd intrinsics that I updated earlier, this gets rid
of 20 intrinsics.

1ff446fef6 Change Neon table lookup (VTBL) and table extension (VTBX) intrinsics to
take the table vectors as separate arguments, instead of the previous
approach where they were combined into one big vector.

9e699cc726 Add new intrinsics for Neon VTRN, VZIP and VUZP operations. Modeling these
as vector shuffles did not work out well.  Shuffles that produce double-wide
vectors accurately represent the operation but make it hard to do anything
with the results.  I considered splitting them up into 2 shuffles, one to
write each register separately, but there doesn't seem to be a good way to
reunite them for codegen.

b7d0c90c44 Change Neon VLDn intrinsics to return multiple values instead of really
wide vectors.  Likewise, change VSTn intrinsics to take separate arguments
for each vector in a multi-vector struct.  Adjust tests accordingly.

cd8eb8b60a Change NEON vldN/vstN intrinsics to specify "N" as an immediate operand
instead of having a separate intrinsic for each value.

4dbbfe3571 Swap order of arguments to vst[34]* intrinsics. This matches the order
used by both the user-visible intrinsics defined by ARM and the
corresponding GCC builtins.

5bafff36c7 Add support for ARM's Advanced SIMD (NEON) instruction set.
This is still a work in progress but most of the NEON instruction set
is supported.

cdcc3e6e12 Modify the intrinsics pattern to separate out the "return" types from the
"parameter" types. An intrinsic can now return a multiple return values like
this:

  def add_with_overflow : Intrinsic<[llvm_i32_ty, llvm_i1_ty],
                                    [LLVMMatchType<0>, LLVMMatchType<0>]>;
