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.

This chagne just renames some sys::Path methods to ensure they are not
misused. The Path documentation now divides methods into two dimensions:
Path/Disk and accessor/mutator. Path accessors and mutators only operate
on the Path object itself without making any disk accesses. Disk accessors
and mutators will also access or modify the file system. Because of the
potentially destructive nature of disk mutators, it was decided that all
such methods should end in the work "Disk" to ensure the user recognizes
that the change will occur on the file system. This patch makes that
change. The method name changes are:
makeReadable -> makeReadableOnDisk
makeWriteable -> makeWriteableOnDisk
makeExecutable -> makeExecutableOnDisk
setStatusInfo -> setStatusInfoOnDisk
createDirectory -> createDirectoryOnDisk
createFile -> createFileOnDisk
createTemporaryFile -> createTemporaryFileOnDisk
destroy -> eraseFromDisk
rename -> renamePathOnDisk
These changes pass the Linux Deja Gnu tests.

Get rid of the difference between file paths and directory paths. The Path
class now simply stores a path that can refer to either a file or a
directory. This required various changes in the implementation and interface
of the class with the corresponding impact to its users. Doxygen comments were
also updated to reflect these changes. Interface changes are:
appendDirectory -> appendComponent
appendFile -> appendComponent
elideDirectory -> eraseComponent
elideFile -> eraseComponent
elideSuffix -> eraseSuffix
renameFile -> rename
setDirectory -> set
setFile -> set
Changes pass Dejagnu and llvm-test/SingleSource tests.

compilation. This change has been waiting in the wings for a long time but
since Misha just did a global change, I figured now was the time to commit
it.

This list does not provide the ability to go backwards in the list (its
more of an unordered collection, stored in the shape of a list).
This change means that use iterators are now only forward iterators, not
bidirectional.
This improves the memory usage of use lists from '5 + 4*#use' per value to
'1 + 4*#use'. While it would be better to reduce the multiplied factor,
I'm not smart enough to do so. This list also has slightly more efficient
operators for manipulating list nodes (a few less loads/stores), due to not
needing to be able to iterate backwards through the list.
This change reduces the memory footprint required to hold 176.gcc from
66.025M -> 57.687M, a 14% reduction. It also speeds up the compiler,
7.73% in the case of bytecode loading alone (release build loading 176.gcc).

This file was schizophrenic when it came to representing sizes. In some
cases it represented them as 'unsigneds', which are not enough for 64-bit
hosts. In other cases, it represented them as uint64_t's, which are
inefficient for 32-bit hosts.
This patch unifies all of the sizes to use size_t instead.

Replace RunProgramWithTimeout with an inline function that calls
sys::Program::ExecuteAndWait. This is now just a convenience function.

file name instead of using std::string.
* Get rid of extraneous "toString" calls.
* Change "removeFile" to sys::Path::destroyFile()

sys::Path::makeUnique and sys::CopyFile, respectively.

Remove AllocateRWXMemory as it is not used any more in LLVM. The function
has been replaced with sys::Memory::AllocateRWX several months ago.

Remove the MakeFileReadable and MakeFileExecutable functions which are no
longer present in LLVM. They have been replaced with the sys::Path methods
makeReadable and makeExecutable, respectively.

The ReadFileIntoAddressSpace and UnmapFileFromAddressSpace functions are no
longer used by LLVM. Remove them. Replacement functionality for both
functions is now encapsulated in the sys::MappedFile class.

LLVM headers from your own project, so I moved the check a bit down into
the Unix case to avoid the hassle... Here is a patch

It is left in place in case anyone wants to updated it for GCC 3.4 or
re-use it for earlier versions of GCC where it works.

This is still probably not correct, or portable, but it'll do for now.

Hence, it should save us some recompiling after re-configures.

absolute position on the command line. Similarly allow any cl::list to
use the method getPosition(n) to retrieve the absolute position of the nth
option in the list. This provides support for two things: (a) options like
-l that are actually positional and their order of occurrence matters when
they are intermixed with positional arguments like "a.o"; and (b) options
like -x LANG which affect only the positional arguments that come after
the option. In both cases, knowing the absolute position of a given option
helps.
