Adding support for vscale

that should be explicitly made clear in the patches. it sounds very
much like it's only suitable for statically-allocated
arrays-of-vectorisable-types:
typedef vec4 float[4]; // SEW=32,LMUL=4 probably
static vec4 globalvec[1024]; // vscale == 1024 here
or, would it be intended for use inside functions - again statically-allocated?
int somefn(void) {
static vec4 localvec[1024]; // vscale == 1024 here
}
*or*, would it be intended to be used like this?
int somefn(num_of_vec4s) {
static vec4 localvec[num_of_vec4s]...

ok, this starts to narrow down the definition. i'm attempting to get
clarity on what it means. so...
