[Interpreter] Refactor bytecode generator test suite. Bytecode expectations have been moved to external (.golden) files, one per test. Each test in the suite builds a representation of the the compiled bytecode using BytecodeExpectationsPrinter. The output is then compared to the golden file. If the comparision fails, a textual diff can be used to identify the discrepancies. Only the test snippets are left in the cc file, which also allows to make it more compact and meaningful. Leaving the snippets in the cc file was a deliberate choice to allow keeping the "truth" about the tests in the cc file, which will rarely change, as opposed to golden files. Golden files can be generated and kept up to date using generate-bytecode-expectations, which also means that the test suite can be batch updated whenever the bytecode or golden format changes. The golden format has been slightly amended (no more comments about `void*`, add size of the bytecode array) following the consideration made while converting the tests. There is also a fix: BytecodeExpectationsPrinter::top_level_ was left uninitialized, leading to undefined behaviour.

[interpreter] Make FunctionEntry StackCheck bytecodes implicit FunctionEntry StackChecks is one of the two cases where we generate a StackCheck bytecode. In these cases, we do stack check against the js limit (not to be confused with the real js limit). Their purpose is to be able to interrupt the running code. We can omit the FunctionEntry StackCheck by embedding its code into the InterpreterEntryTrampoline builtin. We save one bytecode per interpreted function. This change has rippling effects for optimized code, as well as the deoptimizer.

[inspector] improve return position of explicit return in non-async function Goal of this CL: explicit return from non-async function has position after return expression as return position (will unblock [1]). BytecodeArrayBuilder has SetStatementPosition and SetExpressionPosition methods. If one of these methods is called then next generated bytecode will get passed position. It's general treatment for most cases. Unfortunately it doesn't work for Returns: - debugger requires source positions exactly on kReturn bytecode in stepping implementation, - BytecodeGenerator::BuildReturn and BytecodeGenerator::BuildAsyncReturn generates more then one bytecode and general solution will put return position on first generated bytecode, - it's not easy to split BuildReturn function into two parts to allow something like following in BytecodeGenerator::VisitReturnStatement since generated bytecodes are actually controlled by execution_control(). ..->BuildReturnPrologue(); ..->SetReturnPosition(stmt); ..->Return(); In this CL we pass ReturnStatement through ExecutionControl and use it for position when we emit return bytecode right here. So this CL only will improve return position for returns inside of non-async functions, I'll address async functions later.

constant pool: [
[Interpreter] Remove constant pool type in tests For historical reasons, the interpreter's bytecode expectations tests required a type for the constant pool. This had two disadvantages: 1. Strings and numbers were not visible in mixed pools, and 2. Mismatches of pool types (e.g. when rebaselining) would cause parser errors This removes the pool types, making everything 'mixed', but appending the values to string and number valued constants. Specifying a pool type in the *.golden header now prints a warning (for backwards compatibility).

[ast] Move AstValue implementation into Literal This eliminates the AstValue class, effectively moving its implementation into the Literal AstNode. This should cause no difference in behavior, but it does signal some shifts in the underlying system. Biggest changes include: - Reduction in AST memory usage - No duplicate HeapNumbers in Ignition constant pools - Non-String values are allocated either at constant pool creation time (or at boilerplate creation time for literals), rather than at AstValueFactory::Internalize() time. There are a variety of test-only/debug-only changes due to these switches as well.
