Eliminate an explicit use of the LLVM basic block, using getParent instead,
which simplifies the code

Add non-const MachineBasicBlock::getParent() accessor method.

MBBs start out as #-1. When a MBB is added to a MachineFunction, it

Add non-const MachineBasicBlock::getParent() accessor method.

MBBs start out as #-1. When a MBB is added to a MachineFunction, it
gets the next available unique MBB number. If it is removed from a
MachineFunction, it goes back to being #-1.

Refactor rewinding code for finding the first terminator of a basic
block into MachineBasicBlock::getFirstTerminator().

This also fixes a bug in the implementation of the above in both

Refactor rewinding code for finding the first terminator of a basic
block into MachineBasicBlock::getFirstTerminator().

This also fixes a bug in the implementation of the above in both
RegAllocLocal and InstrSched, where instructions where added after the
terminator if the basic block's only instruction was a terminator (it
shouldn't matter for RegAllocLocal since this case never occurs in
practice).
