Update the cmake and autoconf build system to compile polly
as a shared library if it is checked out into tools/polly. In case
polly is not checked out, nothing changes.
This models the way clang can be added to llvm if checked out to tools/clang.

Also rebuild configure.

*BSD(s) have environ(7) in CRT startup and cannot resolve "environ" at linking llvm.so.
environ(7) is used inlib/System/Unix/Program.inc.

A RegionPass is executed like a LoopPass but on the regions detected by the
RegionInfo pass instead of the loops detected by the LoopInfo pass.

Get rid of static constructors for pass registration.  Instead, every pass exposes an initializeMyPassFunction(), which
must be called in the pass's constructor.  This function uses static dependency declarations to recursively initialize
the pass's dependencies.

Clients that only create passes through the createFooPass() APIs will require no changes.  Clients that want to use the
CommandLine options for passes will need to manually call the appropriate initialization functions in PassInitialization.h
before parsing commandline arguments.

I have tested this with all standard configurations of clang and llvm-gcc on Darwin.  It is possible that there are problems
with the static dependencies that will only be visible with non-standard options.  If you encounter any crash in pass
registration/creation, please send the testcase to me directly.

is different from what the code now uses in a two ways: NamedMDNodes
were considered Values and included in the numbering, and the
function-local metadata counter wasn't reset between functions.

The later problem breaks lazy deserialization, so instead of trying
to emulate the old numbering, just drop the old metadata. The only
in-tree use case is debug info with LTO, where the QOI loss is
considered acceptable.

Follow the same logic in the LoopPass, ModulePass and CallGraphSCCPass printers,
as it was already used in the BasicBlockPass and FunctionPass printers. This is
more consistent.

The other option would have been to completely disable dumping the analysis
information. However, as this information is the only information printed if the
-analysis flag is set, calling opt would not do anything at all.
