[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.

Reland: [ignition] Add call bytecodes for undefined receiver Adds a collection of call bytecodes which have an implicit undefined receiver argument, for cases such as global calls where we know that the receiver has to be undefined. This way we can skip an LdaUndefined, decrease bytecode register pressure, and set a more accurate ConvertReceiverMode on the interpreter and TurboFan call. As a side effect, the "normal" Call bytecode now becomes a rare case (only with calls and super property calls), so we get rid of its 0-2 argument special cases and modify CallProperty[N] to use the NotNullOrUndefined ConvertReceiverMode.

Reland: [ignition] Add call bytecodes for undefined receiver Adds a collection of call bytecodes which have an implicit undefined receiver argument, for cases such as global calls where we know that the receiver has to be undefined. This way we can skip an LdaUndefined, decrease bytecode register pressure, and set a more accurate ConvertReceiverMode on the interpreter and TurboFan call. As a side effect, the "normal" Call bytecode now becomes a rare case (only with calls and super property calls), so we get rid of its 0-2 argument special cases and modify CallProperty[N] to use the NotNullOrUndefined ConvertReceiverMode.

Revert "Reland: [TypeFeedbackVector] Store optimized code in the vector" This reverts commit 662aa425bac00f468d2b2e91a149b5f35e2a4ad3. Reason for revert: Crashing on Canary BUG=chromium:718891 Original change's description: > Reland: [TypeFeedbackVector] Store optimized code in the vector > > Since the feedback vector is itself a native context structure, why > not store optimized code for a function in there rather than in > a map from native context to code?

[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.

[ic] Pass name to LoadGlobalIC again. The reasons are: 1) The names dictionaries in the feedback metadata seems to consume a lot of memory and the idea didn't payoff. 2) The absence of a name parameter blocks data handlers support in LoadGlobalIC.
