39fd659d68 Fix tracing code support to link in the tracing routines if neccesary.
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.

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

2df1f74b97 Runtime routines to support tracing.

The hash table should be separated out into a separate file
since that is generic.  The rest of this code is pretty small.

1e2ddcf741 Hash pointer values to a sequence number to get identical results from

dabb41d93d Numerous bug fixes:
-- 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
