Chris Lattner a6fc9de9fc remove use of SmallVector from Path::makeUnique. Path::makeUnique
is not used by anything performance sensitive, so just use std::string.

Chris Lattner e6be85661d eliminate an extraneous use of SmallVector in a case where
a fixed size buffer is perfectly fine.

Torok Edwin 022336adf7 Add "generic" fallback.
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.).

Torok Edwin abdc1c274b Using _MSC_VER there was wrong, better just use the already existing ifdefs for
x86 CPU detection for the X86 getHostCPUName too, and create a simple
getHostCPUName that returns "generic" for all else.

Torok Edwin 5c9429fa47 Enable CPU detection when using MS VS 2k8 too.
MSVS2k8 doesn't define __i386__, hence all the CPU detection code was disabled.
Enable it by looking for _MSC_VER.

Oscar Fuentes 8b6d88d2f8 Fixes the Atomic implementation if compiled by MSVC compiler.
sys::cas_flag should be long on this platform, InterlockedAdd() is
defined only for the Itanium architecture (according to MSDN).

Kovarththanan Rajaratnam 4b9f0b6720 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.

Fixes PR5635.

Benjamin Kramer 713fd3564a Revert CPU detection code to return "generic" instead of an empty string in case
of failure. The x86 target didn't like empty cpu names and broke x86 tests on
non-x86 buildbots.

Daniel Dunbar 241d01b590 Add llvm::sys::getHostCPUName, for detecting the LLVM name for the host CPU.
- This is an initial step towards -march=native support in Clang, and towards
   eliminating host dependencies in the targets. See PR5389.

Ted Kremenek b5cd6233b1 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.

Mikhail Glushenkov 88e98fec70 Remove the GetProcessId() call from Win32/Program.inc, take 2.
GetProcessId() was introduced only in Windows XP, and we want to support earlier
versions.

Daniel Dunbar 4c7b0ca05b Add a magic LLVM_DISABLE_CRT_DEBUG environment variable which we check in RegisterHandler and use to disable the Win32 crash dialogs. These are a major blocker to any kind of automated testing.
Also, tweak the 'lit' test runner to set this variable unconditionally.

Mikhail Glushenkov 0adf07eb9e 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.

Dan Gohman e592923603 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.

Chris Lattner c521f54198 Prune #includes from llvm/Linker.h and llvm/System/Path.h,
forcing them down into various .cpp files.

This change also:
1. Renames TimeValue::toString() and Path::toString() to ::str()
   for similarity with the STL.
2. Removes all stream insertion support for sys::Path, forcing
   clients to call .str().
3. Removes a use of Config/alloca.h from bugpoint, using smallvector
   instead.
4. Weans llvm-db off <iostream>

sys::Path really needs to be gutted, but I don't have the desire to
do it at this point.
