RVV is variable length vector but also has 256 bit VLS mode vector.
This test is vectorized as:

Use 256 bit vector, so remove XFAIL for 256 bits vector.
gcc/testsuite/ChangeLog:
* gcc.dg/vect/bb-slp-43.c: Fix XPASS for RVV.
So will this create a FAIL if someone runs the testsuite with the
autovec preference set to scalable? Or are the fallbacks to VLS still
available when we prefer scalable vectors?
