included when using global symbols to ask the linker for the addresses of
various functions. One of the symbols was actually getting declared by a
header included in DynamicLibrary.cpp, which conflicted with the "extern void*"
declaration in SearchForAddressOfSpecialSymbol().

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.

DynamicLibrary::SearchForAddressOfSymbol and force them to have "C"
linkage.
Interestingly, GCC treats the block-scoped "extern" declarations we
previously had as if they were extern "C" declarations (or, at least,
were in the global namespace), so that GCC bug papered over this LLVM
bug. Clang and EDG get the linkage correct; this new variant seems to
work for both GCC and Clang.

gcc warned that the function may not have a return value, indeed
for non-intel and non-amd X86 CPUs it is right (VIA, etc.).

x86 CPU detection for the X86 getHostCPUName too, and create a simple
getHostCPUName that returns "generic" for all else.

MSVS2k8 doesn't define __i386__, hence all the CPU detection code was disabled.
Enable it by looking for _MSC_VER.

sys::cas_flag should be long on this platform, InterlockedAdd() is
defined only for the Itanium architecture (according to MSDN).

create a std::string from a NULL pointer.
Fixes PR5635.

- This is an initial step towards -march=native support in Clang, and towards
eliminating host dependencies in the targets. See PR5389.

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.

- MingW needs -lpsapi (in ${LIBS}) linked after -lLLVMSystem.
Noticed by Ronald Pijnacker!
- Some parts of the System library must be build with exceptions on windows.

GetProcessId was introduced only in XP. As a bonus, this change makes Program
objects copyable, since Program is now basically a PID.

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.
