TBAA: remove !tbaa from testing cases if not used.

This will make it easier to turn on struct-path aware TBAA since the metadata
format will change.

misched: Infrastructure for weak DAG edges.

This adds support for weak DAG edges to the general scheduling
infrastructure in preparation for MachineScheduler support for
heuristics based on weak edges.

sched: fix latency of memory dependence chain edges for consistency.

For store->load dependencies that may alias, we should always use
TrueMemOrderLatency, which may eventually become a subtarget hook. In
effect, we should guarantee at least TrueMemOrderLatency on at least
one DAG path from a store to a may-alias load.

This should fix the standard mode as well as -enable-aa-sched-mi".
