IBM Z: gen-vect-11/32: Set min-vect-loop-bound param back to default
In the Z backend we still set min-vect-loop-bound to 2 to work around
corner cases where awkward epilogue code gets generated in the
vectorizer. This has a particular bad impact when vectorizing loops
with a low iteration count. Due to this we do not vectorize the loop
in gen-vect-11/32 - what actually is a pity.
The patch sets min-vect-loop-bound back to the default value of 0 in
order to enable vectorization.

* gcc.dg/tree-ssa/gen-vect-11.c: Add --param min-vect-loop-bound=0
for IBM Z.
* gcc.dg/tree-ssa/gen-vect-23.c: Likewise.
