fun emitGetVariableOffRamp(getOperation: L2Operation, variable: L2ReadBoxedOperand, targetSemanticValue: L2SemanticValue, makeImmutable: Boolean): L2ReadBoxedOperand
Emit the specified variable-reading instruction, and an off-ramp to deal with the case that the variable is unassigned.
Return
The L2ReadBoxedOperand into which the variable's value will be written, including having made it immutable if requested.
Parameters

The location of the variable.
