b28303ef74 [PassManager] Tuning Memory Usage of AnalysisUsage 
We were using unneccessarily large initial sizes for these SmallVectors.  This was wasting around 50kb of memory for the O3 pipeline, even after the uniquing changes.  We're still using around 20kb which is a bit much, but it's definitely better.  This is about a 6% improvement in total O3 memory usage.

Note: The raw data on structure size which were used to pick these thresholds can be found in the review thread.

2eeb3460a8 [LPM] Teach the legacy pass manager to support *using* an analysis 
without *requiring* it.

This allows a pass indicate that it will use an analysis if available
(through getAnalysisIfAvailable). When the pass manager knows this, it
will refrain from deleting that analysis if it can. Naturally, it will
still get invalidated at the correct time. These passes are not
considered when scheduling the pass pipeline, so typically they will
require manual scheduling, but this may also allow passes with
getAnalysisIfAvailable to find the analysis more often if nothing after
them requires that analysis and it wasn't invalidated.

I don't have a particular use case with the current passes, but with my
new structure for alias analyses, this will be very useful. We want to
allow people to customize the set of AAs available by scheduling
additional passes. These's aren't ever *required* for obvious reasons.
So we need some way to mark in the legacy pass manager that they will
still be used if available.

This is essentially how analysis groups already work. But this makes the
feature generally available and more explicit. It should allow the AA
change to not impact how people trigger a custom alias analysis being
available at a certain point in compilation.

ca305491f6 Sort the #include lines for the include/... tree with the script. 
AKA: Recompile *ALL* the source code!

This one went much better. No manual edits here. I spot-checked for
silliness and grep-checked for really broken edits and everything seemed
good. It all still compiles. Yell if you see something that looks goofy.
