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.

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.

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.
