Make the Win32 code exception free (untested/uncompiled) which forced some
interface changes which had ripple effect. This should be the last of 797.

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:
                DEBUG BUILD                RELEASE BUILD

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

Final removal of exceptions from lib/System and adjustment of users to
accommodate.

llvm-svn: 29846

Eliminate exception throwing from Path::renamePathOnDisk and adjust its
users correspondingly.

llvm-svn: 29843

Remove exception throwing from Path::getDirectoryContents and its users.

llvm-svn: 29841

Remove exceptions from the Path::create*OnDisk methods. Update their users
to handle error messages via arguments and result codes.

llvm-svn: 29840

Adjust code to compensate for Path class interface change.

llvm-svn: 29837

Change the Path::make*OnDisk methods exception free and adjust their usage.

just return MinTime if that should ever happen.

Make MappedFile not throw any exceptions.

llvm-svn: 29816

Fix a bug in my last patch that botched file redirection by using explicit
scoping of if statements.

llvm-svn: 29808

Remove all exception code from Program.inc and implement its new interface
with an ErrMsg string argument.

llvm-svn: 29790

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.

the erasure of non-file paths like /dev/null.

Update ltld.[ch] to version 1.5.22.
Correct the notes about updating these tools (autoconf/README.TXT)
Add configure options for getting the correct option for including a whole
archive when linking.

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.
