new testcase for nested functions

push bytecode decompressor out through APIs.  Now the bytecode reader
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.

Fix Transforms/DeadArgElim/2007-02-07-FuncRename.ll, fallout from PR411.
This happened because deadargelim now causes VMCore to auto-rename every
function that it hacks arguments out of.  Because it hacks arguments out of
functions in a non-deterministic order, this caused the resultant numbering
to be nondet.  The fix is to just be careful to not rename functions!

Although targets are not required to support integers > 64bits, TargetData
must in order for backends that do want to support large integer types to be
able to function. Consequently, don't assert if the bitwidth > 64 bits
when computing the size and alignment. Instead, compute the size by rounding
up to the next even number of bytes for the size. Compute the alignment
as the same as the LongABIAlignment. These provide reasonable defaults
that the target can override.

With the last change, we no longer need both directions of mapping from
BBNumbers.  Instead of using a bi-directional mapping, just use a single

1.2485s.

StableBasicBlockNumbering is conceptually just a wrapper around UniqueVector,
so we should actually use a UniqueVector to implement it.

For PR411:
Adjust to changes in Module interface:
getMainFunction() -> getFunction("main")
getNamedFunction(X) -> getFunction(X)

For PR411:
Change getNamedFunction -> getFunction
Make llvm-extract run the StripDeadPrototypes pass.

git-svn-id: https://llvm.org/svn/llvm-project/llvm/trunk@33921 91177308-0d34-0410-b5e6-96231b3b80d8

For PR411:
Clean up the Module::getFunction interface. getMainFunction and
getNamedFunction are now gone. Just use getFunction instead.

git-svn-id: https://llvm.org/svn/llvm-project/llvm/trunk@33920 91177308-0d34-0410-b5e6-96231b3b80d8

For PR411:
This test is not particularly useful without type planes.

For PR411:
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.

Add a class APInt to represent arbitrary precision constant integral values.
It is a functional replacement for common case integer type like "unsigned",
"uint64_t", but also allows non-byte-width integer type and large integer
value types such as 3-bits, 15-bits, or more than 64-bits of precision. For
more details, see pr1043.
