JSSpecCompiler: Prepare for building SSA
...
This commit introduces NamedVariableDeclaration and
SSAVariableDeclaration and allows storing both of them in Variable node.
Also, it adds additional structures in FunctionDefinition and
BasicBlock, which will be used to store SSA form related information.

JSSpecCompiler: Add control flow graph simplification pass
...
It removes empty `BasicBlock`s with an unconditional jump continuation
and then removes unreferenced blocks from the graph.

JSSpecCompiler: Adopt more C++ terminology
...
Let's not use strange names like `ExecutionContext`, which nobody will
understand in the future.

JSSpecCompiler: Add reference resolving pass
...
It replaces UnresolvedReference with Variable, FunctionPointer, or
SlotName nodes. Also, it gathers all variable names from their
declarations.

JSSpecCompiler: Make nodes inherit from Statement or Expression
...
The distinction between them will become important during CFG building.

JSSpecCompiler: Add if branch merging pass
...
It merges standalone IfBranch/ElseIfBranch nodes into IfElseIfChain
nodes. This will ease CFG generation later.

JSSpecCompiler: Allow storing error text in ErrorNode
...
This will be the main way to communicate errors from compilation passes.

JSSpecCompiler: Restrict usage of NodeSubtreePointer
...
This class stores a non-owning raw pointer to a member of `Node`, so
extra care is needed to ensure that referenced `Node`s will be alive
by the time `NodeSubtreePointer` is used. Since we only need to use this
class while traversing AST in `RecursiveASTVisitor`, access to class
methods can be restricted using `Badge<RecursiveASTVisitor>`.

JSSpecCompiler: Introduce Function and ExecutionContext classes
...
Currently, they are not extremely useful, but the plan is to store
all function-local state in JSSpecCompiler::Function and all
"translation unit" state in ExecutionContext.
