This is required because trace code can insert calls to functions that
are (now) in an LLVM library, not a native library.
This change makes it easier to use the tracing code because the native
link options don't have to change, and it fits in a lot better with the
LLVM model.

directory.
If the test code needs to be resurrected in the future, it should be moved
into the test/Programs directory, linking with tracelib.

Currently includes code to hash pointers to sequence numbers.
The hash table should be separated out into a separate file
since that is generic. The rest of this code is pretty small.

Methods now take MachineCodeForInstruction& as an argument and record
temporary values in it directly, instead of return the temps.
Really simplifies callers.

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.

-- 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

instructions generated for integer multiply
