Major addition to bugpoint: ability to debug code generators (LLC and LLI).
The C backend is assumed correct and is used to generate shared objects to be
loaded by the other two code generators.
LLC debugging should be functional now, LLI needs a few more additions to work,
the major one is renaming of external functions to call the JIT lazy function
resolver.
Bugpoint now has a command-line switch -mode with options 'compile' and
'codegen' to debug appropriate portions of tools.
ExecutionDriver.cpp: Added implementations of AbstractInterpreter for LLC and
GCC, broke out common code within other tools, and added ability to generate C
code with CBE individually, without executing the program, and the GCC tool can
generate executables shared objects or executables.
If no reference output is specified to Bugpoint, it will be generated with CBE,
because it is already assumed to be correct for the purposes of debugging using
this method. As a result, many functions now accept as an optional parameter a
shared object to be loaded in, if specified.

Allow folding several instructions into casts, which can simplify a lot
of codes. For example,

%tmp.3 = shr short %t1.1, ubyte 8 ; <short> [#uses=1]
%tmp.5 = cast short %tmp.3 to int ; <int> [#uses=1]

%tmp.8 = cast int %tmp.7 to short ; <short> [#uses=1]

Stop passing ostreams around: we already have one perfectly good ostream
and we can all share it.
Stop stashing a pointer to TargetData in the Pass object, because that will
lead to a crash if there are no functions in the module (ouch!) Instead,
use addRequired() and getAnalysis(), like we always should have done.
Move the check for ConstantExpr up before the check for isPrimitiveType,
because we need to be able to catch e.g. ubyte (cast bool false to ubyte),
whose type is primitive but which is nevertheless a ConstantExpr, by calling
our specialized handler instead of the AsmWriter. This would result in
assembler errors when we would try to output something like ".byte (cast
bool false to ubyte)".
