Add preparePassManager() hook. This allows each pass to check whether

current active pass manager is appropriate or not.
A loop pass may consider current LPPassManager in appropraite if loop
pass is not preserving analysis information that is used by other
passes managed by current LPPassManager. In such situation, loop pass
can pop current LPPassManager from the PMStack using this hook
and use new LPPassManager for itself.

Make APInt a little more friendly to its users:
...
* Add support for + and - of a uint64_t.
* Make trunc/sext/zext return *this so it can be chained with other ops
* Add smin, smax, umin, umax functions for getting min/max values.

Implement the first step towards arbitrary precision integer support in
LLVM. The APInt class provides arbitrary precision arithmetic and value
representation. This patch changes ConstantInt to use APInt as its value
representation without supporting bit widths > 64 yet. That change will
come after ConstantFolding handles bit widths > 64 bits.

Implement support for non-standard integer bit widths of any size. The
...
rules alignment is to pick the alignment that corresponds to the smallest
specified alignment that is larger than the bit width of the type or the
largest specified integer alignment if none are larger than the bitwidth
of the type. For the byte size, the size returned is the next larger
multiple of the alignment for that type (using the above rule). This patch
also changes bit widths from "short" to "uint32_t" to ensure there are
enough bits to specify any bit width that LLVM can handle (currently 2^23);
16-bits isn't enough.

3. Better names for things.
4. Arrange constructors so they all take bit width first.
5. Add named signed and unsigned comparison functions and remove the
corresponding operators.
6. Remove operator&& and operator|| but provide a getBoolValue function which
converts to bool as comparison against 0. This allows the normal && and
|| operators to be used as if (X.getBoolValue() && Y.getBoolValue())
Note: this still doesn't function 100% yet. I'm working on the bugs now.

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.

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

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

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.

Introduce new UnarySDNode/BinarySDNode/TernarySDNode nodes, which coallocate
...
their operands with the node itself. This reduces malloc traffic for operand
lists. This reduces isel time on kc++ from 2.6164 to 2.5570s, about 2.3%.

Add a new SDNode ctor and InitOperands method. This allows the operands for
...
an SDNode to be allocated as part of the node itself, instead of being a
separate new[]'d object. Switch HandleSDNode, LoadSDNode, and StoreSDNode
to use this mechanism. This saves one heap allocation and free for each node
of this type that is allocated. This reduces isel time from 2.7638 to 2.6164s
on kc++, which is a 5.6% speedup.
