This patch add supports for single architecture mach-o files (the current implementation only support Universal Binary), and solve the signature conflict between java class and Universal Binary magics.
Note that this function will always returned dynamic library for Universal Binaries (like the current implementation) because the binary type is not include in the file header."

In the unix variant, rename RedirectFD to RedirectIO and let that function
handle empty and null paths instead of doing that in the caller 3 times. This
is the same as win32 already does it.
In the win32 variant, use Path::isEmpty() instead of checking the resulting
c_str() manually. This is the same as unix already does it.

This method allows one to create a directory, and optionally create all parent
directories that do not exist.
The original implementation would require that *all* directories along a path
are writable by the user, including directories that already exist. For example,
suppose we wanted to create the directory "/tmp/foo/bar", and the directory
"/tmp" already exists, but not "/tmp/foo". Since "/tmp" is writable by all
users, the original implementation would work, and create "/tmp/foo", followed
by "/tmp/bar".
A problem occurred, however if one wanted to created the directory
"/Users/myuser/bar" (or equivalently "/home/myuser/bar"), and "/Users/myuser"
already existed and is writable by the current user. The directory
"/User/myuser" is writable by the user, but "/User" is not. The original
implementation of createDirectoryOnDisk would return with failure since "/User"
is not writable, even though "/User/mysuser" is writable.
The new implementation works by recursively creating parents as needed, and thus
doesn't need to check the permissions on every directory in a path.

I added the lexing files to the VStudio projects and removed the .l files from the
VStudio projects. There was a problem with use of strtoll in TGLexer.cpp and Chris
suggested switching to strtol, so that's included here.
Additionally, this checkin adds minimal x64 builds to the VStudio builds. Build issues
related to x64 in the windows specific files for DynamicLibrary.inc and Singals.inc
are worked around, but not ultimately solved. Binaries used to be stored in
...\win32\{Debug|Release}
but are now kept in
...\win32\bin\{win32|x64}\{Debug|Release}
intermediate files will continue to be stored in the individual project directories under
win32.
Some names will likely change in the future to reflect that the vstudio projects
are no longer 32-bit only, but I wanted to get things up and running today so kept away
from bigger restructuring.

the removal of directories. Using std::remove is indiscriminate and can
lead to the removal of things like /dev/null if run as root. The
Path::eraseFromDisk method ensures that we only ever remove regular files
or directories, but never character or block special nodes. This should
clear up the problem with usage like: llvm-as -o /dev/null which is used
in the llvm-test makefiles.

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

so its makefile was changed to always add -lpthread to the link line.
