This makes it much more useful for running benchmarks that are missing
prototypes for some functions.

for malloc and free. Lots of crufty benchmarks are using stuff like:
char *malloc();
void free();
to forward declare malloc and free. Now we recognize and raise these forms

the random debugging macros scattered throughout llvm.
The new DEBUG(x) macro should be used instead of special purpose debug macros.

to certain classes. This is nice because it means that in header files we can
just declare a value, and still have that value be set based on a command-line
argument. The difference is now that the #include of CommandLine.h does not
need to go into the header file as well.

* Provide a #include of <malloc.h> so that the sun C compiler does not
miscompile malloc function calls

May be slightly less efficient but significantly reduces special
cases interfaces in code generation.

lli and llc. This is controlled with options -tracehash on|off.
Also, added an option to specify which functions should be traced.
Particularly useful to reduce output volume in basic-block tracing.

array and struct indexes.
Update operand values in CallArgsDescriptor (a new class)
when replacing constant values with immediates.

-- passing FP arguments to functions with more than 6 arguments
-- passing FP arguments to varargs functions
-- passing FP arguments to functions with no prototypes
-- incorrect coloring for CC registers (both int and FP): interferences
were being completely ignored for int CC and were considered but no
spills were marked for fp CC!
Also some code improvements:
-- better interface to generating machine instr for common cases
(many places still need to be updated to use this interface)
-- annotations on MachineInstr to communicate information from
one codegen phase to another (now used to pass information about
CALL/JMPLCALL operands from selection to register allocation)
-- all sizes and offests in class TargetData are uint64_t instead of uint

Make all sizes and offsets uint64_t instead of uint.
Fixed GetIndexedOffset to handle mixed array and struct indices.

instructions generated for integer multiply
-- passing FP arguments to functions with more than 6 arguments
-- passing FP arguments to varargs functions
-- passing FP arguments to functions with no prototypes
-- incorrect stack frame size when padding a section
-- folding getelementptr operations with mixed array and struct indexes
-- use uint64_t instead of uint for constant offsets in mem operands

which global variables would have name collisions if they were not mangled,

* Add optimization to rank computation to not recursively search when
unneccesary.
* More agressively negate expressions to open reassociation opportunities.
* Linearize (A+B)+(C+D) into ((A+B)+C)+D

By making sure to consider binary expressions identical if their operands
are backwards, but swappable.
