This converts existing "preparser" tests that expect a certain exception
message to be produced into "message" tests. Thereby we get much better
coverage because the former test suite degraded by now to just check
whether each test case threw or not, the exception message was not being
checked at all.
This also deprecates the ability of "preparser" to specify that single
test cases based on JS files are expected to throw, "messages" is far
superior, use that test suite instead.

After histrogram timer added time recaling functionality,
some events, e.g. parse, histogram timer generates event log ending with 'MicroSeconds'.
Since ProfViz can't recorgnize it, this patch cuts off 'MicroSeconds' postfix.

port 5096492f1b (r34627)
original commit message:
- Eliminate stubs with a variable number of arguments.
(That only worked due to their very limited use. These
stubs' interface descriptors were basically lying
about their number of args, which will fail when used
generically.)
- Fix all CallApi*Stubs' interface descriptors to no
longer lie about their arguments.
- Unify CallApi*Stub, for * in Function, Accessor,
FunctionWithFixedArgs.
(Since these are now all doing the same thing.)
- Rename the unified stub (and interface descriptors) to
*ApiCallback*, since that's really what they're doing.
- Refuse inlining an API callback if its number of
parameters exceeds the supported number of args.

Now that the destructuring flags are gone, we always call
CheckAndRewriteReferenceExpression, so unified the two methods again.
Also cleaned up the code within, e.g. removing unnecessary Scanner::Location
construction.

When the TypedArray iterator constructor code path was added, a technically
incorrect optimization was added which uses the arraylike code path on array
arguments, even though the %ArrayIterator% could have been monkey-patched
to give different behavior. A previous patch removed this optimization, and
this patch restores it due to the huge performance regression that resulted.
The optimization was previously removed in

This adds a function to the sancov_merger that merges the
output files of one swarming shard in parallel. This will
be called from the infrastructure when collecting/merging
swarming results.
The tool will be called subsequently for each shard. On
the first call, the target dir will be empty and the sancov
files will just be moved.

This is because compiler.cc is awesome. There are cases where we do not
yet have a SharedFunctionInfo that can tell us whether we are compiling
a generator function, we query the FunctionLiteral instead.

This ensures our optimizing compilers as well as the interpreter are
never tasked with compiling the generator-resuming builtin methods. The
corresponding intrinsics for those methods are not supported and it is
not possible to provide a C++ reference implementation for them. We do
this by assigning builtin function ids to them that we can recognize
during the compiler dispatch.
Note that this also affects the interpreter, because methods having a
builtin function id assigned are not interpreted ({function_data} field
is overlapping). If this ever changes we can still do an early check in
the compiler dispatch (similar to the optimizing compilers) easily.
This applies to the following methods:
- Generator.prototype.next (calls Runtime_GeneratorNext).
- Generator.prototype.return (calls Runtime_GeneratorReturn).
- Generator.prototype.throw (calls Runtime_GeneratorThrow).
