One can easily go over this limit when doing 64-bit arithmetic

to be able to just emit an instruction of the intended execution size
from the visitor and let the lowering pass deal with this restriction
transparently.

all instructions that use the accumulator implicitly (which the SIMD

default constructor for each field.  For built-in basic types, the
default constructor does nothing.  The later will, according to
http://stackoverflow.com/questions/2417065/does-the-default-constructor-initialize-built-in-types)
perform value-initialization of the type.  For built-in types this means
initializing to zero.

The per_vertex_accumulator constructor is:

    per_vertex_accumulator::per_vertex_accumulator()
       : fields(),
         num_fields(0)
    {
    }

This is the second form of constructor, so the glsl_struct_field
objects were previously zero initialized.  With the addition of an empty
