do and the risks of lazy compilation in the presence of threads.

Add a CodeGenOpt::Less level to match -O1. It'll be used by clients which do not want post-regalloc scheduling.

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.

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.

 - 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.

To simplify the upcoming context-on-type change, switch all command line tools to using the default global context for now.

This will let us to hardwire stuff to the global context in the short term while the API is sorted out.

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.

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.
