Matt Pharr db5db5aefd Add native support for (AO)SOA data layout.
There's now a SOA variability class (in addition to uniform,
varying, and unbound variability); the SOA factor must be a
positive power of 2.

When applied to a type, the leaf elements of the type (i.e.
atomic types, pointer types, and enum types) are widened out
into arrays of the given SOA factor.  For example, given

struct Point { float x, y, z; };

Then "soa<8> Point" has a memory layout of "float x[8], y[8],
z[8]".

Furthermore, array indexing syntax has been augmented so that
when indexing into arrays of SOA-variability data, the two-stage
indexing (first into the array of soa<> elements and then into
the leaf arrays of SOA data) is performed automatically.
