Infer sets of variables in each reactive scope

Browse Source 
Adds a new pass `InferReactiveScopeVariables` which determines the sets of 
variables (by Identifier) which "construct together" and belong in the same 
reactive scope. Concretely, `Identifier` gets a new property `scope: ScopeId`, 
and this pass assigns each identifier a ScopeId value. The algorithm iterates 
over all instructions in all blocks (in a single pass) and builds up disjoint 
sets of identifiers that appear as mutable operands in the same instruction. 

The algorithm is relatively simple (especially since I had already implemented a 
union-find data structure): however looking at some examples reinforced that 
other planned todos around alias analysis are really important. We also have to 
think more about what "mutable lifetime" means in the context of SSA: currently 
variables that are reassigned (but never "mutated", eg bc they're assigned a 
value type) never appear as mutable.

* For each mutable variable, infers a reactive scope which will construct that
* variable. Variables that co-mutate are assigned to the same reactive scope.
* This pass does *not* infer the set of instructions necessary to compute each
* variable/scope, only the set of variables that will be computed by each scope.
*
* Examples:
* ```javascript
* // Mutable arguments
* let x = {};
* let y = [];
* foo(x, y); // both args mutable, could alias each other
* y.push(x); // y is part of callee, counts as operand
*
* let z = {};
* y.push(z);
*
* // Mutable assignment
* let x = {};
* let y = [];
* x.y = y; // trivial aliasing
* ```
*
* More generally, all mutable operands (incl lvalue) of an instruction must go in the
* same scope.
*
* ## Implementation
*
* 1. Iterate over all instructions in all blocks (order does not matter, single pass),
* and create disjoint sets ({@link DisjointSet}) for each set of operands that
* mutate together per above rules.
* 2. Iterate the contents of each set, and assign a new {@link ScopeId} to each set,
* and update the `scope` property of each item in that set to that scope id.
*
* ## Other Issues Uncovered
*
* 1. Mutable lifetimes need to account for aliasing.
*
* ```javascript
* let x = {};
* let y = [];
* x.y = y; // RHS is not considered mutable here bc not further mutation
* mutate(x); // bc y is aliased here, it should still be considered mutable above
* ```
*
* 2. Mutable lifetimes need to account for SSA reassignment.
*
* ```javascript
* // y is never considered mutable bc SSA treats subsequent assignments as distinct identifiers
* let y;
* if (cond) {
* y = ...;
* } else {
* y = ...;
* }
* ```
