6726b6d75a Remove VISIBILITY_HIDDEN from class/struct found inside anonymous namespaces. 
Chris claims we should never have visibility_hidden inside any .cpp file but
that's still not true even after this commit.

9450b0e1a6 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.

5c12adaa8b 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.

c23197a26f llvm_unreachable->llvm_unreachable(0), LLVM_UNREACHABLE->llvm_unreachable. 
This adds location info for all llvm_unreachable calls (which is a macro now) in
!NDEBUG builds.
In NDEBUG builds location info and the message is off (it only prints
"UREACHABLE executed").

c25e7581b9 assert(0) -> LLVM_UNREACHABLE. 
Make llvm_unreachable take an optional string, thus moving the cerr<< out of
line.
LLVM_UNREACHABLE is now a simple wrapper that makes the message go away for
NDEBUG builds.

1970a89a49 Call doInitialization(), releaseMemory(), and doFinalization() for on-the-fly passes as well. 
Also don't call finalizers for LoopPass if initialization was not called.
Add a unittest that tests that these methods are called, in the proper
order, and the correct number of times.

d6f16587ab 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

488dc6732d 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.
