Avoid changing behaviour for everyone who's used to the traditional ghostview
UI, especially since it knows how to stay in the foreground unlike xdg-open.
Amendment to r210147.

Amend r210001 to use the classic fallback order behaviour if the requested
graphing program isn't found.

Replace the crufty build-time configure checks for program paths with
equivalent runtime logic.
This lets users install graphing tools as needed without having to reconfigure
and rebuild LLVM, while eliminating a long chain of inappropriate compile
dependencies that included GUI programs and the windowing system.
Additional features:
* Support the OS X 'open' command to view graphs generated by any of the
Graphviz utilities. This is an alternative to the Graphviz OS X UI which is
no longer available on Mountain Lion.
* Produce informative log output upon failure to indicate which programs can
be installed to view graphs.
Ping me if this doesn't work for your particular environment.

It was only used to implement ExecuteAndWait and ExecuteNoWait. Expose just
those two functions and make Execute and Wait implementations details.

Sooooo many of these had incorrect or strange main module includes.
I have manually inspected all of these, and fixed the main module
include to be the nearest plausible thing I could find. If you own or
care about any of these source files, I encourage you to take some time
and check that these edits were sensible. I can't have broken anything
(I strictly added headers, and reordered them, never removed), but they
may not be the headers you'd really like to identify as containing the
API being implemented.
Many forward declarations and missing includes were added to a header
files to allow them to parse cleanly when included first. The main
module rule does in fact have its merits. =]

forcing them down into various .cpp files.
This change also:
1. Renames TimeValue::toString() and Path::toString() to ::str()
for similarity with the STL.
2. Removes all stream insertion support for sys::Path, forcing
clients to call .str().
3. Removes a use of Config/alloca.h from bugpoint, using smallvector
instead.
4. Weans llvm-db off <iostream>
sys::Path really needs to be gutted, but I don't have the desire to
do it at this point.

with very large graphs, where dot isn't necessarily the
most visually pleasing way of looking at the graph.

provides a way to quickly dump a bunch of graph information to dot files
and display them. It's a timesaver when working on large systems.

Adjust usage of the ExecuteAndWait function to use the last argument which
is the ErrMsg string. This is necessitated because this function no longer
throws exceptions on error.

Make sys::Program::ExecuteAndWait not throw exceptions and update any
affected code. It now return -9999 to signal that the program couldn't be
executed. Only one case (in bugpoint) actually examines the result code.

Refactor the Graph writing code to use a common implementation which is
now in lib/Support/GraphWriter.cpp. This completes the PR.
