53835b8081 Link with test/Libraries/libinstr32.a for runtime routines
supporting tracing.  That should be moved to a "runtime" directory.

2df1f74b97 Runtime routines to support tracing.
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.

c864fde15c New function CreateSignExtensionInstructions.
Methods now take MachineCodeForInstruction& as an argument and record
temporary values in it directly, instead of return the temps.
Really simplifies callers.

0243ff9e62 InstrnsBefore and InstrnsAfter are now vectors instead of deques.
May be slightly less efficient but significantly reduces special
cases interfaces in code generation.

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

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
