The test "assertThrows(builder.instantiate)" threw a TypeError before,
which made the test pass, but not because of the feature we wanted to
test.
This CL fixes the test to call builder.instantiate correctly, and also
tests for the correct error message.
Drive-by fix: Fix {expected} and {found} parameters in assertThrows.

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.

to be usable by a PluralRules implementation. Along the way, I found
and fixed a couple minor issues where options handling differed from
the specification, and removed some dead code. Regression tests are

resembles the specification plus this editorial change which is out

Before serializing an external string for a native source, we replace
its resource field with the type and index of the native source. Upon
deserialization, we restore the resource.
This change also removes the native source caches with a more straight-

of having multiple output registers, which would be necessary if we unpacked
the entire I16x8 register.

into a single destination register with signed or unsigned saturation. These
could have been separated into half operations, but this is simpler to
implement with SSE, AVX, and is acceptable on ARM. It also avoids adding
operations that only modify half of their destination register.
