b0f45f192c Rather than using an ifdef on the target to zero out fields, 
just use memset to zero the entire struct.

b049874698 Factor out the handler work from SignalHandler into a helper function, 
and change llvm::sys::RunInterruptHandlers to call that function directly
instead of calling SignalHandler, because the rest of SignalHandler
invokes side effects which aren't appropriate, including raising the
signal.

152b2bc046 This is horrible. Split the difference, and declare 'environ' on all non-Darwin 
platforms to unbreak the darwin and linux builds. The BSD folks should feel
free to change the #if, if this breaks them.

22b58ac393 make Program::Execute use posix_spawn on systems that support it, 
as it is more efficient than fork/exec.

Thanks to Eric for adding the autoconf check.  It would be nice if
a cmake guru could add a cmake check for posix_spawn as well.

58964f4bee Fix a false-positive memory leak in code using RemoveFileOnSignal(). Because 
libstdc++'s std::string class points to the interior of an allocation, valgrind
reports strings still alive at program termination as possible leaks.  I didn't
use a ManagedStatic for this because System can't depend on Support.

46925cc515 Fix TimeValue::now() on Unix. 
TimeValue()::now().toEpochTime() is supposed to be the same as time(),
but it wasn't, because toEpoch subtracted PosixZeroTime, but now()
didn't add PosixZeroTime!
Add a unittest to check this works.

435a9894a7 This patch ensures that Path::GetMainExecutable is able to handle the 
case where realpath() fails. When this occurs we segfault trying to
create a std::string from a NULL pointer.

b9ff937285 Use 'waitpid' instead of 'wait'. Basing Program::Wait() on 'wait()' prevents it being correct within a multithreaded context. 
This address: PR 5277 (Program::Wait is unsafe to call from multiple threads).

Note: If waitpid() turns out to be non-portable, we can add more autoconf magic, or look into
another solution.

3b1f94a1fc Get rid of GetProcessId in Win32/Program.inc. 
GetProcessId was introduced only in XP. As a bonus, this change makes Program
objects copyable, since Program is now basically a PID.

149ac38d37 Fix llvm-extract's "writing bitcode to a terminal" warning, which wasn't 
working. To support this, add an is_displayed() function to raw_ostream,
and generalize Process::StandardOutIsDisplayed and friends in order to
support it.

Also, call RemoveFileOnSignal before creating a file instead of after, so
that the file isn't left behind if the program is interrupted between when
the file is created and RemoveFileOnSignal is called.

While here, add a -S to llvm-extract and port it to IRReader so that it
supports assembly input.
