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.

byte 12 not byte 15. Hopefully this fixes the llvm-ld warning on Darwin.

Make the sys::Path::getFileStatus function more efficient by having it
return a pointer to the FileStatus structure rather than copy it. Adjust
uses of the function accordingly. Also, fix some memory issues in sys::Path.

windows case needs to be improved.

* Add a method: bool isAbsolute() const, which determines if the path name
is absolute or not.
* Implement caching of file status information in the Path object. Allow it
to be updated forcefully or lazily re-fetched from the cached value.

Make the Win32 code exception free (untested/uncompiled) which forced some

Final commit for this bug. This removes the last EH holdouts in LLVM
and turns off exception support by using the -fno-exceptions option. This
leads to the following reduction in library and executable sizes:

Adjust implementation to match the new interface after exception handling
was removed in the Unix verison. NOTE: this hasn't been compiled yet!

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.

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.

Update ltld.[ch] to version 1.5.22.
Correct the notes about updating these tools (autoconf/README.TXT)

instead of throwing an exception. This reduces the amount of code that is
exposed to exceptions (e.g. FileUtilities), though it is clearly only one step
along the way.

Put the rest of lib/System into LinkAllVMCore.h. This makes all of
lib/System available to programs that #include LinkALlVMCore.h so that
loadable modules linked into those programs can depend on all of lib/System
being available.

1. Move IncludeFile.h to System library
2. Move IncludeFile.cpp to System library
3. #1 and #2 required to prevent cyclic library dependencies for libSystem
4. Convert all existing uses of Support/IncludeFile.h to System/IncludeFile.h
5. Add IncludeFile support to various lib/System classes.
6. Add new lib/System classes to LinkAllVMCore.h
All this in an attempt to pull in lib/System to what's required for VMCore

This reduces the # syscalls executed.
