gcc/ChangeLog:

         * config/riscv/riscv-passes.def (INSERT_PASS_BEFORE): Reorder VSETVL 
PASS.
It'd be useful to know the motivation here, I could easily see someone 
in the future finding a case where the location of the vsetvl gets 
influenced by some dead code that would have been removed by the DCE 
pass.  Then they're going to want to know the motivation behind the 
current pass placement.

So, OK after adding a comment describing why the pass is placed where it is.
