Fix 2 bugs in FoldGetElemChain so index vector is not modified
when no GEPs are folded in, and so a hasLeadingZero is computed
only for the last folded GEP, not the one after that if any.

is platform independant afterall.
* Object orientize the functions, cleanup code a bit. Instead of static
global functions, the helpers for instruction selection are now part of
the InstructionSelection Pass class.

Significant changes to correctly spill CC registers and to correctly
...
handle conditional move instructions:
-- cpMem<->Reg functions now support CC registers (int and FP) correctly.
-- Scratch registers must be explicitly provided to cpMem<->Reg when
needed, since CC regs need one to be copied to/from memory.
-- CC regs are saved to a scratch register instead of stack.
-- All regs used by a instruction are now recorded in MachineInstr::regsUsed,
since regs used to save values *across* an instruction are not obvious
either from the operands or from the LiveVar sets.
-- An (explicit or implicit) operand may now be both a def and a use.
This is needed for conditional move operations.
So an operand may need spill code both before and after the instruction.
-- class MachineCodeForBasicBlock is now an annotation on BasicBlock.

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
