4424043996 reapply my timer rewrite with a change for PassManager to store 
timers by pointer instead of by-value.

1d0b06c139 Remove the #include of Pass.h from PassManager.h. This breaks a significant 
#include dependency, as frontends commonly pull in PassManager.h.

bd50ec69e4 Move the dominator verification code out of special code embedded within 
the PassManager code into a regular verifyAnalysis method.

Also, reorganize loop verification. Make the LoopPass infrastructure
call verifyLoop as needed instead of having LoopInfo::verifyAnalysis
check every loop in the function after each looop pass. Add a new
command-line argument, -verify-loop-info, to enable the expensive
full checking.

09f5f7f190 Extend the StartPassTimer and StopPassTimer functions so that the 
code that stops the timer doesn't have to search to find the timer
object before it stops the timer. This avoids a lock acquisition
and a few other things done with the timer running.

33852b4f35 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

abf6c9aa1d 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.

better, gives the compiler a chance to validate the cast and reduces warnings

8ee9065162 Use 'static const char' instead of 'static const int'. 
Due to darwin gcc bug, one version of darwin linker coalesces
static const int, which defauts PassID based pass identification.
