ART: Disable vectorization for debuggable graphs.

SuspendCheck environment is incorrectly initialized with
a stale version of the loop induction variable (a pre-loop one)
for vectorized loops. The value can be retrieved from a
corresponding stack maps only in case of asynchronous
deoptimization in debuggable mode. Thus this workaround forbids
loop optimizations on debuggable graphs so the bug is never
triggered.

Test: test-art-target, test-art-host.
Bug: 138601207
