There is no way to create a POLY_INT_CST at the gimple level for riscv as
__riscv_vlenb does not fold down to one but the testcase would have be:
Something like:
```
#include <riscv_vector.h>
#pragma GCC target("arch=rv64gc")
__attribute__((noinline))
static int g(int a)
{
return a + 1;
}
#pragma GCC target("arch=rv64gcv")
int f(void) {
int t = __riscv_vlenb();
return g(t);
}
```
