make memset inference significantly more powerful: it can now handle

memsets that initialize "structs of arrays" and other store sequences
that are not sequential. This is still only enabled if you pass

analyzed the perf regressions when -form-memset-from-stores is passed
either, but this causes no make check regressions.

Avoid creating chain dependencies from CopyToReg nodes to load and store
...
nodes. This doesn't currently have much impact the generated code, but it
does produce simpler-looking SelectionDAGs, and consequently
simpler-looking ScheduleDAGs, because there are fewer spurious
dependencies.
In particular, CopyValueToVirtualRegister now uses the entry node as the
input chain dependency for new CopyToReg nodes instead of calling getRoot
and depending on the most recent memory reference.
Also, rename UnorderedChains to PendingExports and pull it up from being
a local variable in SelectionDAGISel::BuildSelectionDAG to being a
member variable of SelectionDAGISel, so that it doesn't have to be
passed around to all the places that need it.

Speed-up the SumOfUnscheduledPredsOfSuccs by introducing a new function
...
called LimitedSumOfUnscheduledPredsOfSuccs. It terminates the computation
after a given treshold is reached. This new function is always faster, but
brings real wins only on bigger test-cases.
The old function SumOfUnscheduledPredsOfSuccs is left in-place for now and therefore a warning about an unused static function is produced.
