I took some liberties and quoted fewer characters than before,
based on an article from MSDN which says that only certain characters
cause an arg to require quoting. This seems to be incorrect, though,
and worse it seems to be a difference in Windows version. The bot
that fails is Windows 7, and I can't reproduce the failure on Win
10. But it's definitely related to quoting and special characters,
because both tests that fail have a * in the argument, which is one
of the special characters that would cause an argument to be quoted
before but not any longer after the new patch.
Since I don't have Win 7, all I can do is just guess that I need to
restore the old quoting rules. So this patch does that in hopes that
it fixes the problem on Windows 7.

This reverts commit 65243b6d19143cb7a03f68df0169dcb63e8b4632.
Seems like it's not a flake. It might have something to do with
the '*' character being in a command line.

There were a few linux compilation failures, but other than that
I think this was just a flake that caused the tests to fail. I'm
going to resubmit and see if the failures go away, if not I'll
revert again.

This reverts commit 10d2e88e87150a35dc367ba30716189d2af26774.
This is causing some test failures for some reason, reverting
while I investigate.

This function was internal to Program.inc, but I've needed this
on several occasions when I've had to use CreateProcess without
llvm's sys::Execute functions. In doing so, I noticed that the
function was written using unsafe C-string access and was pretty
hard to understand / make sense of, so I've also re-written the
functions to use more modern LLVM constructs.

See r331124 for how I made a list of files missing the include.
I then ran this Python script:
for f in open('filelist.txt'):
f = f.strip()
fl = open(f).readlines()
found = False
for i in xrange(len(fl)):
p = '#include "llvm/'
if not fl[i].startswith(p):
continue
if fl[i][len(p):] > 'Config':
fl.insert(i, '#include "llvm/Config/llvm-config.h"\n')
found = True
break
if not found:
print 'not found', f
else:
open(f, 'w').write(''.join(fl))
and then looked through everything with `svn diff | diffstat -l | xargs -n 1000 gvim -p`
and tried to fix include ordering and whatnot.
No intended behavior change.

LLVM_ON_WIN32 is set exactly with MSVC and MinGW (but not Cygwin) in
HandleLLVMOptions.cmake, which is where _WIN32 defined too. Just use the
default macro instead of a reinvented one.
See thread "Replacing LLVM_ON_WIN32 with just _WIN32" on llvm-dev and cfe-dev.
No intended behavior change.
This moves over all uses of the macro, but doesn't remove the definition
of it in (llvm-)config.h yet.

Summary:
Change the type of the Redirects parameter of llvm::sys::ExecuteAndWait,
ExecuteNoWait and other APIs that wrap them from `const StringRef **` to
`ArrayRef<Optional<StringRef>>`, which is safer and simplifies the use of these
APIs (no more local StringRef variables just to get a pointer to).
Corresponding clang changes will be posted as a separate patch.

This is a minimal change to remove the header. I will remove the occurrences
of "using std::error_code" in a followup patch.

- New ProcessInfo class to encapsulate information about child processes.
- Generalized the Wait() to support non-blocking wait on child processes.
- ExecuteNoWait() now returns a ProcessInfo object with information about
the launched child. Users will be able to use this object to
perform non-blocking wait.
- ExecuteNoWait() now accepts an ExecutionFailed param that tells if execution
failed or not.
These changes will allow users to implement basic process parallel
tools.

Execute's Data parameter is now optional, so we won't allocate memory
for it on Windows and we'll close the process handle.
The Unix code should probably do something similar to avoid accumulation
of zombie children that haven't been waited on.
Tested on Linux and Windows.

It was only used to implement ExecuteAndWait and ExecuteNoWait. Expose just
those two functions and make Execute and Wait implementations details.

if execution failed. ExecuteAndWait returns -1 upon an execution failure, but
checking the return value isn't sufficient because the wait command may
return -1 as well. This new parameter is to be used by the clang driver in a
subsequent commit.

This change allows bugpoint to pinpoint the "opt" pass and bitcode
segment responsible for a crash caused by miscompilation. At least it
works well for me now, without having to create any custom execution
wrappers.
