Speculatively revert r108813, in an attempt to get the self-host buildbots working again.  I don't see why this patch
would cause them to fail the way they are, but none of the other intervening patches seem likely either.

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.

Begin the painful process of tearing apart the rat'ss nest that is Constants.cpp and ConstantFold.cpp.
This involves temporarily hard wiring some parts to use the global context.  This isn't ideal, but it's
the only way I could figure out to make this process vaguely incremental.

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.

Patches for Clang and LLVM-GCC to follow.

linear instruction simplification stages or not, so I left it in.

Sometimes when bugpointing a crash the bugpoint-reduced-simplified.bc reproduces
a totally different bug than the original one ("GV doesn't have initializer").
Although its useful to report that bug too, I need a way to reduce the original
bug, hence I introduced -disable-global-remove.

This patch replaces the SymbolTable class with ValueSymbolTable which does
not support types planes. This means that all symbol names in LLVM must now
be unique. The patch addresses the necessary changes to deal with this and
removes code no longer needed as a result. This completes the bulk of the
changes for this PR. Some cleanup patches will follow.
