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.

vector of MachineInstr* to return multiple ones.

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

(many places still need to be updated to use this interface).

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

llvm-svn: 2642

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

-- correct sign extensions for integer casts and for shift-by-constant
   instructions generated for integer multiply
-- passing FP arguments to functions with more than 6 arguments

-- folding getelementptr operations with mixed array and struct indexes

* 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
