11cd3dd9fc Take out the debug info probe stuff. It's making some changes to 
the PassManager annoying and should be reimplemented as a decorator
on top of existing passes (as should the timing data).

3c9be3c4cc Add pass printer passes in the right place. 
The pass pointer should never be referenced after sending it to
schedulePass(), which may delete the pass. To fix this bug I had to
clean up the design leading to more goodness.

You may notice now that any non-analysis pass is printed. So things like loop-simplify and lcssa show up, while target lib, target data, alias analysis do not show up. Normally, analysis don't mutate the IR, but you can now check this by using both -print-after and -print-before. The effects of analysis will now show up in between the two.

The llc path is still in bad shape. But I'll be improving it in my next checkin. Meanwhile, print-machineinstrs still works the same way. With print-before/after, many llc passes that were not printed before now are, some of these should be converted to analysis. A few very important passes, isel and scheduler, are not properly initialized, so not printed.

39b3306530 Basic PassManager diagnostics. 
Added asserts whenever attempting to use a potentially
uninitialized pass. This helps people trying to develop a new pass and
people trying to understand the bug reports filed by the former people.

73d68195ce Introduce DebugInfoProbe. This is used to monitor how llvm optimizer is treating debugging information. 
It generates output that lools like

8 times line number info lost by Scalar Replacement of Aggregates (SSAUp) 
1 times line number info lost by Simplify well-known library calls 
12 times variable info lost by Jump Threading

b09e2e1be4 Make dumpPassStructure be a PMDataManager abstraction, rather than 
a Pass abstraction, since that's the level it's actually used at.
Rename Pass' dumpPassStructure to dumpPass.

This eliminates an awkward use of getAsPass() to convert a PMDataManager*
into a Pass* just to permit a dumpPassStructure call.

5f218b8612 Speculatively revert r108813, in an attempt to get the self-host buildbots working again. I don't see why this patch
