Make the sys::Path::getFileStatus function more efficient by having it
return a pointer to the FileStatus structure rather than copy it. Adjust
uses of the function accordingly. Also, fix some memory issues in sys::Path.

Make Signedness information pervasive throughout all types and values.
There is no easy way to get around this. Because the GEP instruction can
index through an arbitrarily complex value structure, it is necessary to
keep track of signedness information throughout that structure. This change
makes Signedness a full class, capable of representing Signedness in
arbitrarily shaped types. The class is then used throughout llvm-upgrade to
track signedness and differentiate between globals, locals, and functions
based on their signedness.
For PR1243:
This patch also removes bogus warnings about renaming internal globals. It
now only emits such warnings when renaming non-internal globals because
they may affect linkage.

last entry stored in the map could be retrieved for a given integer type.
Propagating the sign information required an invasive change to ensure that
all ValueRef (ValID) instances get the right sign information as well. Also,
put in some assertions to ensure the RenameMap always gives us out the type
that is expected.
This fixes PR1256 and

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.

Since CompilerDriver.cpp revision 1.44, llvmc must be linked against LLVMCore.a (llvm::Module::~Module) and LLVMBCReader.a
(llvm::getBytecodeModuleProvider).

Make llvm-ld more gccld-like by having it run the same set of passes. The
delta was probably due to lack of llvm-ld being maintained. Just another
reason to have only one optimizing linker in in LLVM.
