d614673bb8 This patch ensures that Path::GetMainExecutable is able to handle the 
case where realpath() fails. When this occurs we segfault trying to
create a std::string from a NULL pointer.

Fixes PR5635.

74382b7c69 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.

a7f2a9e69f Make Unix.h:MakeErrMsg separate the prefix and errno string, so we get: 
clang: error: unable to make temporary file: /etc/cc: can't make

instead of 

  clang: error: unable to make temporary file: /etc/cc: can't make
  unique filenamePermission denied

for example.

Also, audited the uses of MakeErrMsg to make the prefix strings
consistent (not end with newline/punctuation/space/": ").
