421fd3929d [wasm] Rename {Get,Set,Tee}Local to Local{Get,Set,Tee}
This brings our constants back in line with the changed spec text. We
already use kExprTableGet and kExprTableSet, but for locals and globals
we still use the old wording.

This renaming is mostly mechanical.

PS1 was created using:
ag -l 'kExpr(Get|Set|Tee)Local' src test | \
  xargs -L1 sed -E 's/kExpr(Get|Set|Tee)Local\b/kExprLocal\1/g' -i

PS2 contains manual fixes.

82d240c736 [test] Introduce assertThrowsAsync
We often use raw assertPromiseResult with {success ==
assertUnreachable} for that. Having a separate helper increases
readability and allows us to generate consistent (and better) error
messages.

e0dc3d2962 [wasm] Reject an exception in the start function on the promise
We assumed that if the ErrorThrower is empty after instantiation, then
instantiation succeeded and an instance exists which we can return.
However, if the start function throws, no instance exists, which caused
a crash. With this CL we handle execeptions thrown by the start
function correctly.

86a2720763 [test] Make assertThrowsEquals use assertSame
The typical use of assertThrowsEquals is to check that a specific
object is thrown. However, assertEquals only does a proper equality
check for primitive types, not for complex types. Using assertSame
does a reference equality check on objects, which is more what you
would expect from assertThrowsEquals. For exception kind testing,
assertThrowsEquals actually did not work correctly, assertThrows is
better for that case.

d6aed4435f [wasm] Use pending exceptions consistently
In our internal code, we should only use pending exceptions. They will
be converted to scheduled exceptions on the API boundary.
Hence, the ErrorThrower just sets a pending exception; it should never
have to think about scheduled exceptions. The new
ScheduledErrorThrower inherits from ErrorThrower and reschedules any
pending exceptions in its destructor (turning them into scheduled
exceptions).
In some situations, there might already be a scheduled exception, e.g.
when calling other API methods (v8::Value::Get). In this case, the
ErrorThrower should also not set another pending exception. For the
reasons mentioned above, this can only be handled in the
ScheduledErrorThrower, which is used the API methods.

This fixes one DCHECK failure and one TODO about scheduled exceptions
if no instance can be created, because the start function throws.

b3ff390364 [wasm] Fix tests and improve error message
The test "assertThrows(builder.instantiate)" threw a TypeError before,
which made the test pass, but not because of the feature we wanted to

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.
