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.

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.

script was defaulting the LLVMGCC variable to "llvm-gcc" if it couldn't
find llvm-gcc and --with-llvmgccdir was not specified. In this case, there
is no llvm-gcc available on the system so we shouldn't assume that the
user's path will find it any better than configure could. The fix is to
default it to an empty string. If LLVMGCC is empty, the makefiles will
avoid building things that depend on llvm-gcc and give a nice warning
message to that effect.

options have been added to the configure script that control which targets
will be used. The options are:
--enable-target-this (default=disabled)
This will specify that the target corresponding to the build host is
the target that will be compiled/used. You can't use this with any of
the other options (they'll be ignored). This is what most people want.
--disable-target-x86 (default=enabled)
This will prevent the X86 target(s) from being compiled/used.
--disable-target-sparc (default=enabled)
This will prevent both SparcV8 and SparcV9 from being compiled/used.
--disable-target-powerpc (default=enabled)
This will prevent the PowerPC target from being compiled/used.
--disable-target-alpha (default=enabled)
This will prevent the Alpha target from being compiled/used.
--disable-target-ia64 (default=enabled)
This will prevent the IA64 target from being compiled/used.
Note that without any of these options, the default behavior is to build
all targets, as is the current practice.
All these options do is set up the substititution variable TARGETS_TO_BUILD
which contains the targets that should be compiled/used. The variable is
intended to be used in the makefiles. Those changes will come later.

Remove checks for many common Unix programs. Our build process currently
assumes they are there and makes no provisions for any other world-views.
(We can add some of these checks back at some later time if it should prove
useful, but right now, we do not need to check to see whether "rm" exists.)
Remove checks for many common standard C headers and functions. We assume
ISO/ANSI C++, and we always use the <cfoo> versions of ANSI C's <foo.h>
headers, so these checks will not help anything.
Edit configure's warning messages for clarity and content.
Change checks for "optional" programs to default to using "true" instead of
"false", so that a failure to find, e.g., etags, will be less likely to result
in make failing.
