Implement the arbitrary bit-width integer feature. The feature allows
integers of any bitwidth (up to 64) to be defined instead of just 1, 8,
16, 32, and 64 bit integers.
This change does several things:
1. Introduces a new Derived Type, IntegerType, to represent the number of
bits in an integer. The Type classes SubclassData field is used to
store the number of bits. This allows 2^23 bits in an integer type.
2. Removes the five integer Type::TypeID values for the 1, 8, 16, 32 and
64-bit integers. These are replaced with just IntegerType which is not
a primitive any more.
3. Adjust the rest of LLVM to account for this change.
Note that while this incremental change lays the foundation for arbitrary
bit-width integers, LLVM has not yet been converted to actually deal with
them in any significant way. Most optimization passes, for example, will
still only deal with the byte-width integer types. Future increments
will rectify this situation.

This patch removes the SetCC instructions and replaces them with the ICmp
and FCmp instructions. The SetCondInst instruction has been removed and
been replaced with ICmpInst and FCmpInst.

The long awaited CAST patch. This introduces 12 new instructions into LLVM
to replace the cast instruction. Corresponding changes throughout LLVM are
provided. This passes llvm-test, llvm/test, and SPEC CPUINT2000 with the
exception of 175.vpr which fails only on a slight floating point output
difference.

This patch converts the old SHR instruction into two instructions,
AShr (Arithmetic) and LShr (Logical). The Shr instructions now are not
dependent on the sign of their operands.

therefore the function being called must be a main() returning an int. The
consequences when these assumptions are false are not good, so don't assume
them.

Move include/Config and include/Support into include/llvm/Config,
include/llvm/ADT and include/llvm/Support. From here on out, all LLVM
public header files must be under include/llvm/.

between different LLVM procedures (though it is unlikely that an LLI
va_list would make sense to an external function, except by chance.)

CurFrame, TraceMode, and the CachedWriter are history.
The ExecutionAnnotations (SlotNumber, InstNumber, and FunctionInfo) are history.
ExecutionContext now keeps Values for each stack frame in a std::map.
printValue() and print() are history.
executeInstruction() is now part of run().

Switch Interpreter and JIT's "run" methods to take a Function and a vector of
GenericValues.
Move (almost all of) the stuff that constructs a canonical call to main()
into lli (new methods "callAsMain", "makeStringVector").
Nuke getCurrentExecutablePath(), enableTracing(), getCurrentFunction(),
isStopped(), and many dead decls from interpreter.
Add linux strdup() support to interpreter.
Make interpreter's atexit handler runner and JIT's runAtExitHandlers() look
more alike, in preparation for refactoring.
atexit() is spelled "atexit", not "at_exit".

Remove printCurrentInstruction, printStackFrame and infoValue
(only used interactively) and other unused methods of Interpreter.
Fold UserInput.cpp containing only callMainFunction() into Interpreter.cpp.
Remove unused Profile flag.

Get rid of support for DebugMode (make it always off).
Mung some comments.
Get rid of interpreter's PROFILE_STRUCTURE_FIELDS and PerformExitStuff
which have been disabled forever.
Get rid of -abort-on-exception (make it always on).
Get rid of user interaction stuff (debug mode innards).
Simplify Interpreter's callMainFunction().

static method here.
Remove some extra blank lines.
ExecutionEngine.h: Add its prototype.
lli.cpp: Call it.
Make creation method for each type of EE into a static method of its
own subclass.
Interpreter/Interpreter.cpp: ExecutionEngine::createInterpreter -->
Interpreter::create
Interpreter/Interpreter.h: Likewise.
JIT/JIT.cpp: ExecutionEngine::createJIT --> VM::create
JIT/VM.h: Likewise.
