as its main datastructure. There are many improvements yet to be made, but
this speeds up opt --std-compile-opts on 447.dealII by 7.3%.

The bcreader counts on "primitive" types being inserted before they are
referenced in other types. With recent changes to the bcwriter, this fact
became exposed since IntegerType is no longer "primitive". We can no longer
count on all IntegerTypes being inserted early. This patch modifies
getOrCreateTypeSlot to insert any sub-type that can't possibly recurse
before we create the slot for the type. This has the benefit of reducing
the number of OpaqueType objects the reader needs to deal with.

vector<vector> to avoid allocations. This speeds up bcwriting of 447.dealII
from 0.8276 to 0.7637s (8.4%).
This concludes this round of proding the bcwriter into submission. Final
speedup from 24.4s to 0.7637s (32x).

of memory, through a combination of DenseMap and SmallVector. This speeds
up bcwriter on 447.dealII from 1.31s to 0.82s (60% faster).

1.83s to 1.32s (39% faster) on 447.dealII.

off. This makes purgeFunction much faster, speeding up bcwriting of 447.dealII
from 6.8->4.6s (47%).

function-local values. This speeds up bcwriting a small 2.2% (10.384->10.156s
on 447.dealII), but paves the way for more important changes.

2. All function-level constants are now incorporated into the module-level
constant pool, since the compaction table was removed. Eliminate extra
work to check for them.
This speeds up the bcwriter from 24.4s to 13.1s on 447.dealII and .73 -> .56s
on kc++ in a release build.

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.
