We don't need an epilogue loop if the main loop can operate on
partial vectors, so this patch disables an associated test.
The alternative would be to force partial-vectors-usage=1
on the command line.
Tested on aarch64-linux-gnu (with and without SVE), arm-linux-gnueabihf
and x86_64-linux-gnu. OK to install?

* gcc.dg/vect/vect-epilogues.c: XFAIL test for epilogue loop
vectorization if vect_partial_vectors_usage_2.
