0ca67332fa Expand i32/i64 CopyToReg f32/f64 to BIT_CONVERT + CopyToReg.

7b2b5c846c - When expanding a bit_convert whose src operand is also to be expanded and 
its expansion result type is equal to the result type of the bit_convert,
e.g. (i64 bit_convert (f64 op)) if FP is not legal
returns the result of the expanded source operand.
- Store f32 / f64 may be expanded to a single store i32/i64.

For now, just grab the stream and perform the output on it directly.

5c2a46052b Proper fix for PR1037: to determine is a VR is a modref, check 1) whether it is 
tied to another oeprand, 2) whether is is being tied to by another operand. So
the destination operand of a two-address MI can be correctly identified.

difference.

a138c6c73a setOperand should not zap the operand list or add implicit operands to an 
instruction.  Doing so breaks the FP stackifier, the alpha branch selector
the sparc fpmover.

This fixes PR1012 and CodeGen/X86/fp-stack-compare.ll

45fb3f3cb2 For PR950: 
First in a series of patches to convert SetCondInst into ICmpInst and
FCmpInst using only two opcodes and having the instructions contain their
predicate value. Nothing uses these classes yet. More patches to follow.

a7bef4a4e4 Minor code layout tweak: if we have something like this: 
if (cond) goto BB2
BB1:
    ...
    return;
BB2:
   ...

Move BB1 to the end of the function so that the code falls through in the
non-return case.  This has the effect of moving assert (and other no-return
call) bodies and return blocks out of loops.

d7de496b23 - Let MachineInstr ctors add implicit def and use operands. Other operands 
will be inserted before these operands. If the opcode changes (by
  setOpcode), the implicit operands are updated as well.
- Added IsKill, IsDead fields to MachineOperand in preparation for changes
  that move kill / dead info to MachineInstr's.
