This assists with getting around configure's late binding values so that
our LLVM variables don't end up with a "NONE" prefix.

If we fail to find a required program, simply set that program to echo
out something that tells the user the situation. That is, instead of just
"true runtest" we now get "echo 'Skipped: runtest not found'".

1. Assertions now default to on for all builds
2. If you want them disabled you must (a) --disable-assertions to configure
or DISABLE_ASSERTIONS=1 to make.

Support detection of a "CVS" directory at configure time to distinguish
whether this is a release build or a "from tree" build. This knowledge is
used to set the defaults for --enable-optimzied and --enable-assertions
options.

1. Check for Perl and only build llvm-config if its available.
2. Add some virtual components
3. Don't depend on "standard" location for Perl, but configured location
4. Document the tool with a POD file.
This version is now ready for testing by users.

macro that controls whether a non-sane program generates an error or
a warning.

Make any header files that are automatically generated be preconditions of
the compilation. This ensures that if a *.h.in file is changed then its
corresponding *.h file gets updated on the next rebuild. Note that this can
lead to confusing (but correct) results if the *.h.in file changed
unsubstantially so that autoheader doesn't update the *.h file. In that case,
manually touch the *.h file in question to restore order. Moral of the story,
if you're going to "touch" a *.in file then modify it substantially.

These patches make threading optional in LLVM. The configuration scripts are now
modified to accept a --disable-threads switch. If this is used, the Mutex class
will be implemented with all functions as no-op. Furthermore, linking against
libpthread will not be done. Finally, the ParallelJIT example needs libpthread
so its makefile was changed to always add -lpthread to the link line.

Previously the script assumed the version number was the last field, now
it assumes it is the first sequence of digits.

for the command line options. This helps with situations where the executable
name sought is too generic and a more meaningful name needs to be used for
the command line options. It also helps satisfy picky project leaders.

* FIND_STD_PROGRAM will find a program in the path or using --with options
and verify that the path/bin/program is executable. Also allows checking
for include files and libraries. If found, USE_PROGRAM is set, otherwise
its not set. Also sets PROGRAM_BIN (bin directory), and PROGRAM_DIR (top
level directory). If headers are found, sets PROGRAM_INC. If libraries
are found, sets PROGRAM_LIB.
* CHECK_PROGRAM_SANITY can be used to run a program with some option that
only produces information output and requires no input. If the output
matches a regular expression, the program passes the sanity check.
Otherwise, an error occurs.

GRAPHVIZ will contain the path to the program if its found (or "echo Graphviz"
if not) and the #define HAVE_GRAPHVIZ will be defined if its found.

This patch completes the changes for making lli thread-safe. Here's the list
of changes:
* The Support/ThreadSupport* files were removed and replaced with the
MutexGuard.h file since all ThreadSupport* declared was a Mutex Guard.
The implementation of MutexGuard.h is now based on sys::Mutex which hides
its implementation and makes it unnecessary to have the -NoSupport.h and
-PThreads.h versions of ThreadSupport.
* All places in ExecutionEngine that previously referred to "Mutex" now
refer to sys::Mutex
* All places in ExecutionEngine that previously referred to "MutexLocker"
now refer to MutexGuard (this is frivolous but I believe the technically
correct name for such a class is "Guard" not a "Locker").
These changes passed all of llvm-test. All we need now are some test cases
that actually use multiple threads.

Make sure that -lpthread gets added to LIBS variable which puts it at the
end of the tools' link commands, if libpthread.a is found.
Add a test for pthread.h so we can use #ifdef HAVE_PTHREAD_H
