Dan Gohman 79fc0e9250 Use WriteAsOperand instead of manually decorating the name for this
debug output. This improves the printing of anonymous values.

Chris Lattner 4c1e9541d3 Sprinkle some PrettyStackEntry magic into the passmanager. With this, we now
get nice and happy stack traces when we crash in an optimizer or codegen.  For
example, an abort put in UnswitchLoops now looks like this:

Stack dump:
0.	Program arguments: clang pr3399.c -S -O3 
1.	<eof> parser at end of file
2.	per-module optimization passes
3.	Running pass 'CallGraph Pass Manager' on module 'pr3399.c'.
4.	Running pass 'Loop Pass Manager' on function '@foo'
5.	Running pass 'Unswitch loops' on basic block '%for.inc'
Abort

Duncan Sands 51495609df Reapply r64301. These uses of "inline" can cause strange
link-time failures when building with optimization.  Just
get rid of them.

Nuno Lopes 0460bb27e0 fix memory leak in pass manager when adding an analysis pass that already existed. as pass manager takes ownership of the added passes, it has to delete the pass if it isnt added to the pass list

Devang Patel fdee7034b3 The pass manager is not able to schedule -loop-deletion -loop-index-split.
The loop-deletion pass does not preserve dom frontier, which is required by
loop-index-split. When the PM checks dom frontier for loop-index-split, it has
already verified that lcssa is availalble. However, new dom frontier forces new
loop pass manager, which does not  have lcssa yet.

The PM should recheck availability of required analysis passes in such cases.

Dan Gohman 73caf5ff10 Change PMTopLevelManager's PassManagers vector element type from
Pass* to PMDataManager*. PMDataManager is more specific than Pass,
so this more accurately describes the objects that are being stored.

This eliminates the need for several dynamic_casts to PMDataManager*.
It does introduce one dynamic_cast though, in dumpPasses(). Give
this one a comment describing why a dynamic_cast is being used.
