[RISCV] Use MCStreamer::emitInstruction instead of calling AsmPrinter::EmitToStreamer. NFC

[topperc]

This allows us to pass the STI we already have cachced instead of AsmPrinter::EmitToStreamer looking it up from the MachineFunction again.

My plan is to make EmitHwasanMemaccessSymbols use RISCVAsmPrinter::EmitToStreamer instead calling MCStreamer::emitInstruction. To do that I need control of the MCSubtargetInfo.

Seems reasonable to me.
