git-svn-id: https://llvm.org/svn/llvm-project/llvm/trunk@685 91177308-0d34-0410-b5e6-96231b3b80d8

Add vector `implicitUses' to class MachineCodeForVMInstr to hold values
that are used by the VM instruction but not explicit operands of the
m/c instruction.

git-svn-id: https://llvm.org/svn/llvm-project/llvm/trunk@684 91177308-0d34-0410-b5e6-96231b3b80d8

Several fixes:
(1) Avoid hard-coding some register numbers.
(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.
(5) Use (unsigned long) 0 for copying a pointer via "add 0, ptr -> ptr2".

Bug fixes:
(1) Ensure that delay slot instructions are not moved out of place (this
    was happening for some CALL instructions).  Basically, we need to
    move all delay slot instructions out of the graph and handle them
    along with the delayed control transfer instruction.
(2) Mark scheduled instructions correctly when instructions are scheduled
    in more than one cycle in a single step (due to delay slots).

(1) Add edges for Values that are written by multiple m/c instructions
(2) Add edges for LLVM operands that are not machine operands (e.g., Call args)
