Note: FastDSE now equals or exceeds the results of old DSE on all of SPEC2000 and SPEC2006. Unless major problems
show up in the testers, it will likely completely replace old DSE in the near future.

api's look like this:
ModuleProvider *getBytecodeModuleProvider(
const std::string &Filename, ///< Name of file to be read
BCDecompressor_t *BCDC = Compressor::decompressToNewBuffer,
std::string* ErrMsg = 0, ///< Optional error message holder
BytecodeHandler* H = 0 ///< Optional handler for reader events
);
This is ugly, but allows a client to say:
getBytecodeModuleProvider("foo", 0);
If they do this, there is no dependency on the compression libraries, saving
codesize.

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.

Step 1: Copy gccas functionality to opt. This endows opt with a new
-std-compile-opts option to get the set of optimization passes that
gccas used. It also adds -disable-inlining and -disable-opt which
both apply only if -std-compile-opts is given. The -strip-debug option
was also removed. It just makes sure that "-strip" gets done early and
is mostly there for compatibility with gccas. Finally, a new
-verify-each option will cause the verify pass to be run after each pass.

adding a temporary wrapper around the ostream to make it friendly to
functions expecting an LLVM stream. This should be fixed in the future.

Turn on -Wunused and -Wno-unused-parameter. Clean up most of the resulting
fall out by removing unused variables. Remaining warnings have to do with
unused functions (I didn't want to delete code without review) and unused
variables in generated code. Maintainers should clean up the remaining
issues when they see them. All changes pass DejaGnu tests and Olden.

Close out this long standing bug by removing the remaining overloaded
virtual functions in LLVM. The -Woverloaded-virtual option is now turned on.

Make sys::Program::ExecuteAndWait not throw exceptions and update any
affected code. It now return -9999 to signal that the program couldn't be
executed. Only one case (in bugpoint) actually examines the result code.

Rid the Assembly Parser of exceptions. This is a really gross hack but it
will do until the Assembly Parser is re-written as a recursive descent.
The basic premise is that wherever the old "ThrowException" function was
called (new name: GenerateError) we set a flag (TriggerError). Every
production checks that flag and calls YYERROR if it is set. Additionally,
each call to ThrowException in the grammar is replaced with GEN_ERROR
which calls GenerateError and then YYERROR immediately. This prevents
the remaining production from continuing after an error condition.

Shrinkify LLVM's footprint by removing the analyze tool and moving its
functionality into the opt tool. THis eliminates one of the largest tools
from LLVM and doesn't make opt much bigger because it already included
most of the analysis passes. To get the old analyze functionality pass
the -analyze option to opt. Note that the integeration here is dead
simple. The "main" of analyze was just copied to opt and invoked if the
-analyze option was given. There may be opportunities for further
integration such as removing the distinction between transform passes
and analysis passes.
To use the analysis functionality, if you previously did this:
analyze $FNAME -domset -disable-verify
you would now do this:
opt -analyze $FNAME -domset -disable-verify
Pretty simple.
