This is mostly a mechanical change to make TargetInstrInfo API take MachineInstr& (instead of MachineInstr* or MachineBasicBlock::iterator) when the argument is expected to be a valid MachineInstr. This is a general API improvement. Although it would be possible to do this one function at a time, that would demand a quadratic amount of churn since many of these functions call each other. Instead I've done everything as a block and just updated what was necessary. This is mostly mechanical fixes: adding and removing `*` and `&` operators. The only non-mechanical change is to split ARMBaseInstrInfo::getOperandLatencyImpl out from ARMBaseInstrInfo::getOperandLatency. Previously, the latter took a `MachineInstr*` which it updated to the instruction bundle leader; now, the latter calls the former either with the same `MachineInstr&` or the bundle leader. As a side effect, this removes a bunch of MachineInstr* to MachineBasicBlock::iterator implicit conversions, a necessary step toward fixing PR26753. Note: I updated WebAssembly, Lanai, and AVR (despite being off-by-default) since it turned out to be easy. I couldn't run tests for AVR since llc doesn't link with it turned on. llvm-svn: 274189
