The hardcoded constant caused a problem for the wasm fuzzer because
when the maximum memory was allocated in a test case, clusterfuzz ran
out of memory. with the command line flag we can set a lower limit
for the fuzzer.
The flag has the value of the constant as its default value, so that
for everything but the fuzzers nothing should change.

Property backing store size for object literals is
the number of constant and named properties (possibly
over-allocating for the same names).
We do not reserve space in the backing store for __proto__.
We do not reserve space in the backing store for index keys.
Currently, we account for index keys in the runtime when iterating
over the boilerplate properties. Since the boilerplate properties
only include the properties up to the first computed property
name, the property backing store size includes space for index keys
if seen after the first computed property.

This adds a new version string that the embedder can set on compile time

In this particular case, we just did a (lhs)op(rhs), ignoring the case
that lhs and rhs might have different signedness.
This CL changes that to use the proper Cmp##op##Impl implementation,

The index input of load and store nodes has to be of type int32. However
it is still possible that this index input was lowered by the
Int64Lowering, for example if the index was a kTruncateInt64ToInt32
node. With this CL we check if there exists a replacement of the index
and if so, use the replacement instead of the original index as the
input for the lowered load and store nodes.

This patch adds destructor to ValueSerializerTest test fixture class
which reset unhandled scheduled exceptions thrown from the current test.
In some cases unhandled scheduled exceptions from current test (eg.
from one test from ValueSerializerTestWithWasm test case) produce that
Context::New(isolate()) from next test's constructor returns NULL.
This error is easily reproduced when unittest file (compiled for ARM or
MIPS simulator) is directly executed (not by tools/run_tests.py script),
so all tests are executed together. When the script is used, each test
from ValueSerializerTestWithWasm test case is separately executed and
unhandled exception from one test doesn't efect to another test from
the same test case.
