Have to save a boolean (setCC) value whenever use is outside the current
basic block.

Mark setCCInstr used as dest. of conditional-move as both a def and a use.

BA instruction no longer has the unused CC argument.

BA has only one argument.
Added LDFSR, LDXFSR, STFSR and STXFSR.
Fixed operands info for RDCCR, WRCCR.

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.
   Also, cpMem<->Reg functions now return a vector of machine instructions.
-- 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.

Other changes:
-- Added several get{Class,Type} functions.
-- Added unified-to-local register number conversion.
-- class MachineCodeForBasicBlock is now an annotation on BasicBlock.
-- Suggest/Color methods may modify the MachineInstr (and always did),
   so don't make that argument const!
-- Caller-saving code doesn't need its special purpose code for
   handling CC registers since cpMem<->Reg handle those correctly now.

An (explicit or implicit) operand may now be both a def and a use.

Avoid deleting individual instructions until AFTER dead blocks have dropped
their references.  This fixes bug:

New testcase that is a distilled form of the other one

Fix "unimplemented features":
   test/Regression/Transforms/FunctionResolve/retmismatch[12].ll

This makes it much more useful for running benchmarks that are missing
prototypes for some functions.

Support programs that do not #include <malloc.h> or give a full prototype
for malloc and free.  Lots of crufty benchmarks are using stuff like:
char *malloc();
void free();

to forward declare malloc and free.  Now we recognize and raise these forms
