f3f063a58e 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

59040c2825 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.

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.

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.

3203639c35 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.

b500f07edf Make the JIT code emitter properly retry and ask for more memory when it runs 
out of memory, and also make the default memory manager allocate more memory
when it runs out.

Also, switch function stubs and global data over to using the BumpPtrAllocator.

This makes it so the JIT no longer mmaps (or the equivalent on Windows) 16 MB
of memory, and instead allocates in 512K slabs.  I suspect this size could go
lower, especially on embedded platforms, now that more slabs can be allocated.

ccaba64332 Eliminate the static constructors and locks from DynamicLibrary.cpp. 
This fixes PR4512 and eliminating static ctors is always good.  Losing
thread safety is unfortunate, but the code is just incredibly poorly
designed.

If someone is interested, the "right" solution is to split
DynamicLibrary.cpp into two separate pieces: a stateless piece in
libsystem, and a simple support file in libsupport that has the
"state" (e.g.  AddSymbol) in managed static objects.

Doing this would both fix memory leaks we already have, as well as make
the code thread safe again.  it would also make sense to move all the
unix specific code in System/DynamicLibrary.cpp into 
System/Unix/DynamicLibrary.inc.
