[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.

Correctly annotate eval origin. There were a couple of issues with it: - interpreter is not supported - the source position was just accidentally correct for full-codegen - the eval origin could have been cached Also fixes a few other places to use AbstractCode.

Reland - Allow lexically declared "arguments" in function scope in sloppy mode.

Only treat possible eval calls going through 'with' as special. This removes the POSSIBLY_EVAL_CALL call type, and instead uses OTHER_CALL or WITH_CALL to decide whether to do the special LOOKUP_SLOT_CALL runtime call to find the callee and possibly update the receiver with the with-object. This means that eval calls out of 'with' blocks can now just do a normal LdaLookupGlobalSlot operation, which can check the context chain for eval extentions and fast-path the lookup if none exist.

Only treat lookup-slot-calls going through 'with' special This replaces LOOKUP_SLOT_CALL with WITH_CALL, and relies on regular lookup-slot handling in variable load to support other lookup slots (variables resolved in the context of sloppy eval). This allows optimizations for such variable loads to kick in for calls as well. We only need special handling for function calls in the context of with, since it changes the receiver of the call from undefined/global to the with-object. This currently doesn't yet make it work for the direct eval call itself, since the POSSIBLY_EVAL_CALL flag is also used to deal with direct eval 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).
