	Get the appropriate local.set opcode for the given register class.
static unsigned	getLocalTeeOpcode (const TargetRegisterClass *RC)
	Get the appropriate local.tee opcode for the given register class.
static MVT	typeForRegClass (const TargetRegisterClass *RC)
	Get the type associated with the given register class.
static MachineInstr *	findStartOfTree (MachineOperand &MO, MachineRegisterInfo &MRI, const WebAssemblyFunctionInfo &MFI)
	Given a MachineOperand of a stackified vreg, return the instruction at the start of the expression tree.
static void	removeFakeUses (MachineFunction &MF)

This file converts any remaining registers into WebAssembly locals.

After register stackification and register coloring, convert non-stackified registers into locals, inserting explicit local.get and local.set instructions.
