characters long.

Jeffrey Yasskin 31faefff92 Move --march, --mcpu, and --mattr from JIT/TargetSelect.cpp to lli.cpp.
llc.cpp also defined these flags, meaning that when I linked all of LLVM's
libraries into a single shared library, llc crashed on startup with duplicate
flag definitions.  This patch passes them through the EngineBuilder into
JIT::selectTarget().

Jeffrey Yasskin 091217be6f Kill ModuleProvider and ghost linkage by inverting the relationship between
Modules and ModuleProviders. Because the "ModuleProvider" simply materializes
GlobalValues now, and doesn't provide modules, it's renamed to
"GVMaterializer". Code that used to need a ModuleProvider to materialize
Functions can now materialize the Functions directly. Functions no longer use a
magic linkage to record that they're materializable; they simply ask the
GVMaterializer.

Because the C ABI must never change, we can't remove LLVMModuleProviderRef or
the functions that refer to it. Instead, because Module now exposes the same
functionality ModuleProvider used to, we store a Module* in any
LLVMModuleProviderRef and translate in the wrapper methods.  The bindings to
other languages still use the ModuleProvider concept.  It would probably be
worth some time to update them to follow the C++ more closely, but I don't
intend to do it.

Fixes http://llvm.org/PR5737 and http://llvm.org/PR5735.

Chris Lattner 7ba0661f27 Stop building RTTI information for *most* llvm libraries. Notable
missing ones are libsupport, libsystem and libvmcore.  libvmcore is
currently blocked on bugpoint, which uses EH.  Once it stops using
EH, we can switch it off.

This #if 0's out 3 unit tests, because gtest requires RTTI information.
Suggestions welcome on how to fix this.

Jeffrey Yasskin aa8814a877 Revert the API changes from r85295 to make it easier for people to build

Jeffrey Yasskin 4567db45b8 Change the JIT to compile eagerly by default as agreed in
http://llvm.org/PR5184, and beef up the comments to describe what both options
do and the risks of lazy compilation in the presence of threads.

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.

Reid Kleckner 1a722d9b73 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.

Daniel Dunbar a78d809abc Switch lli back to using allocate-gvs-with-code behavior.
- Otherwise we get two regressions in llvm-test for applications which run out
   of space.

 - Once the JIT memory manager is improved, this can be switched back.

Owen Anderson 6773d388aa Add a pointer to the owning LLVMContext to Module. This requires threading LLVMContext through a lot
of the bitcode reader and ASM parser APIs, as well as supporting it in all of the tools.

Jeffrey Yasskin 0b08f3d7cc Add a JITEventListener interface that gets called back when a new function is
emitted or the machine code for a function is freed.  Chris mentioned that we
may also want a notification when a stub is emitted, but that'll be a future
change.  I intend to use this to tell oprofile where functions are emitted and
what lines correspond to what addresses.

Reid Spencer e586f2e7f7 1. Handle errors around the ModuleProvider. This is necessary since it is
reading bytecode.
2. The interpreter can delete the ModuleProvider and replace it with
   another so don't depend on it being around after the EE is created.
3. Don't just run llvm_shutdown on exit but actually delete the EE as well.
   This cleans up a vast amount of memory (but not all) that EE retained
   through exit.

Chris Lattner a0e49f2ead push bytecode decompressor out through APIs. Now the bytecode reader
api's look like this:

ModuleProvider *getBytecodeModuleProvider(
  const std::string &Filename,  ///< Name of file to be read
  BCDecompressor_t *BCDC = Compressor::decompressToNewBuffer,
  std::string* ErrMsg = 0,      ///< Optional error message holder
  BytecodeHandler* H = 0        ///< Optional handler for reader events
);

This is ugly, but allows a client to say:

  getBytecodeModuleProvider("foo", 0);

If they do this, there is no dependency on the compression libraries, saving
codesize.
