HeapNumbers and MutableHeapNumber requires alignment for their double
value field but for now this field can be misaligned on 32-bit platforms.
According to code in Heap::GetFillToAlign() function, kDoubleUnaligned
doesn't actually mean "unaligned" but "aligned to half of double".
This CL fixes this misalignment.

If enable_omit_source_positions is true (defaults to false), source
position tables are not generated when compiling bytecode. They will
then be regenerated when exceptions are thrown.
This adds a new function Compiler::CollectSourcePositions which given a
SharedFunctionInfo with bytecode but no source position table re-parses
and regenerates the bytecode but this time with source positions
collection enabled. Note this will reparse all inner functions that
have previously been compiled since the preparse data is no longer
available.
With the flag enabled there still 18 test failures mostly related to
debugging.

We'll let the bytecode compiler and optimizing compilers deal with dead code,
rather than the ast visitors. The problem is that the visitors previously
disagreed upon what was dead. That's bad if necessary visitors omit parts of
the code that the bytecode generator will actually visit.
I did consider removing the AST nodes immediately in the parser, but that
adds overhead and actually broke code coverage. Since dead code shouldn't be
shipped to the browser anyway (and we can still omit it later in the bytecode
generator), I opted for keeping the nodes instead.

The spec specifies that a non-true return values from the trap functions
should be treated as error in the strict mode. With the new lazy feedback
effort inferring the language mode is expensive and causes regression on
these tests. Since the test doesn't actually need to test this, fixing
them to return true would help test the performance of calling the trap
without the unnecessary overhead of inferring the language mode.

That way we can properly walk the active ambiguous stack of expressions and
stop where it's non-ambiguous. In the bug we would have forced context
allocation of "this" in an outer function because an inner function was parsed

ambiguous arrow head scope to be marked, even though the reference came from a

HeapObject::SizeFromMap() was too large to get inlined anyway.
HeapObject::IsFoo() predicates should be implemented in foo-inl.h,
because that's what they depend on.
This patch also fixes up includes: dropping unnecessary ones from
object-inl.h, and adding them in other places that previously
relied on getting them transitively.

The new scheduling reduces the main thread marking performed in
tasks and on allocation. It is based on two counters:
- bytes_marked,
- scheduled_bytes_to_mark.
The bytes_marked accounts marking done both the main thread and
the concurrent threads. The scheduled_bytes_to_mark increases based
on allocated bytes and also based on time passed since the start
of marking. The main thread steps are allowed to mark the minimal
amount if bytes_marked is greater than scheduled_bytes_to_mark.
This also changes tasks posted for marking. Before only normal
tasks were posted. Now delayed tasks are posted if the marker is
ahead of schedule.

For the initial implementation we simply keep the capacity of
the young large object space in sync with the capacity of the
new space. The only subtlety is that we allow at least one
large object independent from its size. So it may exceed the
capacity of the space.
This also fixes setting of the large page flags for incremental
marking.

use the const information in the optimizing compiler if the map is not
an array map or if the map is stable (since stable maps cannot

V8 test suites return tests by loading them into memory up-front. Up-front
loading has memory and loading-time overhead for the testrunner.
This CL converts the test-suites to load tests during the test run in parallel.
After CL, most test suites start running immediately and all test suites start
running after 3 seconds on a modern SSD.
This CL eliminates the 200 MiB memory spikes that causes memory problems in mac
minis.

"this" is a very common expression. By using a single ThisExpression object
we can both avoid allocating many unnecessary VariableProxies and specialize
the resolution of this since we know where it's declared up-front. This also
avoids having to special-case "this" reference handling in the paths that would
behave differently for "this" than for regular references; e.g., with-scopes.
The tricky pieces are due to DebugEvaluate and this/super() used as default
parameters of arrow functions. In the former case we replace the WITH_SCOPE
with FUNCTION_SCOPE so that we make sure that "this" is intercepted, and still
rely on regular dynamic variable lookup. Arrow functions are dealt with by
marking "this" use in ArrowHeadParsingScopes. If the parenthesized expression
ends up being an arrow function, we force context allocate on the outer scope
(and mark "has_this_reference" on the FUNCTION_SCOPE so DebugEvaluate in the
arrow function can expose "this").
The CL also removes the now unused ThisFunction AST node.

Every testsuite configuration consist of at least 30% code duplication.
The code age ranges from 10 years old to 5 years old. Implementing anything that
touches the testsuite code becomes a technical fight to the death.
This CL removes all the duplication by refactoring the common functionality.
This CL contains structural changes without any logical changes % small bug
fixes.

Test262 has a couple of duplicated test files with the identical inside both
"test262/data/test" and "test262/local-tests/test".
Testrunner used to deduplicate the tests, which masked this issue.
This CL removes the obsolete copies in the local-tests.

This is 3-4x faster than using the Utf8Decoder. This matters for proper
parse-time measurements using d8.

Original change's description:
> [test] Check for illegal uses of mjsunit methods
>
> The assertThrows and assertDoesNotThrow methods expect either a
> function to execute, or a string to eval. In several tests however we
> accidentally passed the *result* of the statement to be tested instead
> of the code.
> This CL adds check to catch such error early, and removes wrong uses.
> In most places, we do not need to use assertDoesNotThrow anyway,
> because exceptions are handled as test failures.
>
> Drive-by: Unify catch syntax in mjsunit.js and make sure to propagate
> MjsUnitAssertionErrors correctly.
