Restrict gcc.dg/tree-ssa/ssa-dse-26.c
This restricts the testcase to the target where it exposes the
situation fixed with g:e9d297a15d68121ba5bdd5a76ea71c1916180622
which targets BIT_FIELD_REFs created by fold_truth_andor.
This avoids strange dejagnu limits with overly long target lists
and simplifies the tests.

* gcc.dg/tree-ssa/ssa-dse-26.c: Skip on !lp64 targets,
simplify dump scanning down to one case.
