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.

objdir == srcdir and objdir != srcdir.

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.

so the makefiles can accommodate.

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.

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.

  we actually get the path and not $GRAPHVIZ as the value.
* Add a #define for the gv program (HAVE_GV) and its value LLVM_PATH_GV.

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.

llvm-svn: 22404

* Add check for pthread.h
* Make sure -lpthread gets added to LIBS if its available
