Ruchira Sasanka 24e29431bc Canged ColorCallArg so that when a call arg is directly pushed on to stack 
for argument passing, that instruction is directly added to the InstructionsBefore
set of the called machine instruction - i.e., it is not reordered.

(2) Fix some incorrect branch opcodes.
(3) Don't try to move int register to float register!
(4) If an operand being forwarded is a constant and it doesn't fit
    into the immed field of the copy machine instruction, then
    generate a load-constant instead of a copy.

Chris Lattner 8d44b99844 Chris seems fond of #include <vector>. Fix these. Also convert use list in 
Value to a vector instead of a list.

Move SchedGraph.h & SchedPriorities.h into lib/CodeGen/InstrScheduling

Chris Lattner 22a6a90511 Make a new llvm/Target #include directory. 
Move files from lib/CodeGen/TargetMachine to lib/Target
Move TargetData.h and TargetMachine.h to Target/{Data.h|Machine.h}
Prepare to split TargetMachine.h into several smaller files

Chris Lattner f8464e4b8d Checkin changes to: 
1. Clean up the TargetMachine structure.  No more wierd pointers that have to
   be cast around and taken care of by the target.
2. Instruction Scheduling now takes the schedinfo as an argument.  The same
   should be done with the instinfo, it just isn't now.
