5b6345974b Fix inconsistencies in testrunner variants
Some tests explicitly set the --always-opt flag, but they are not
ignored when the testrunner is invoked with variant="jitless" or
variant="nooptimization".
This CL implies --opt from --always-opt and excludes
--always-opt when the testrunner is invoked with jitless or
nooptimization variants.

18cbf05e8e [gcmole] Re-write gcmole runner in Python
This removes the dependency on Lua for running gcmole, and Python's
expressiveness lets us clean up the code a bit, including getting rid
of global variables, embedding the multiprocessing (removing the need
for a separate `parallel.py`), and using difflib for printing the test
expectation diff.

076687ab85 [asserts] Add combination assert scopes
Add a "combination" assert scope class, which combines multiple existing
assert scopes.  This will allow scopes with functional overlap, e.g.
DisallowGarbageCollection and DisallowHeapAllocation, to share an assert
type rather than rather than requiring users to remember to set both. To
demonstrate this, this redefines DisallowGarbageCollection to a
combination of DisallowHeapAllocation and a new DisallowSafepoints, and
some of the DCHECKs checking both are simplified to only check one or
the other, as appropriate.

The combination classes become subclasses of the existing assert scopes,
so that they can be used in their place as e.g. a function parameter,
e.g. DisallowGarbageCollection can be passed to a function expecting
const DisallowHeapAllocation&.

As a drive-by, this also changes the per-thread assert scopes to use a
bitmask, rather than a bool array, to store their per-thread data. The
per-isolate scopes already used a bitmask, so this unifies the
behaviour between the two.

a18a674bb8 [api] Introduce a single-threaded version of DefaultPlatform
The new platform can be used in combination with --single-threaded.
It disables background threads and thus avoids waiting on mutexes
and condition variables completely, which is useful for V8 embedders
that fork the V8 process after initialization.

As a bonus the new platform allows use to test --single-threaded and
has already uncovered an existing bug in parallel pointer updating code.

This CL stores not just A's immediate parent type on A, but its
entire list of supertypes, and uses that list plus compile-time
knowledge of B's distance to the root type in order to compare
only exactly one of A's supertypes to B.

2388f2c1ef Fix v8windbg failure on non-ptr-compr builds
On builds without pointer compression enabled, v8windbg currently fails
to display information about objects in the Locals pane. This is because
some important code to get a type name was hidden behind a
COMPRESS_POINTERS_BOOL check. The existing cctest
test-v8windbg/V8windbg is sufficient to catch this error, but apparently
nobody ever runs that test in the failing configuration (Windows,
symbol_level = 2, v8_enable_pointer_compression = false).

ea0ccc7ee3 Plumb import assertions through SourceTextModuleDescriptor's ModuleRequestMap
This change plumbs import assertions from SourceTextModuleDescriptor's
ModuleRequestMap into SourceTextModuleInfo via a new ModuleRequest
type, where previously there had been only the specifier.

SourceTextModuleDescriptor::module_map now deduplicates module requests
using the specifier and the import assertions.  Continuing to use the
specifier alone would cause a loss of information in the event that
a module imports from the same specifier multiple times using different
sets of assertions.  Failing to deduplicate at all would result in
multiple requests for statements like `import {a,b,c} from "foo.js"`,
which would be a potential performance issue.  See design doc at
https://docs.google.com/document/d/1yuXgNHSbTAPubT1Mg0JXp5uTrfirkvO1g5cHHCe-LmY
for more detail on this decision.

v8::internal::ModuleRequest holds the assertions as an array of the form
[key1, value1, position1, key2, value2, assertion2, ...].  However the
parser still needs to use a map, since duplicate assertion keys need to
be detected at parse time.  A follow-up  change will ensure that
assertions are sorted using a proper lexicographic sort.

bd75b0ba3e Reland "[torque] allow exported classes with custom C++ class"
This is a reland of 26f10ecd95

Change compared to original CL:
The deserializer changes StrongDescriptorArray to DescriptorArray.
Since this CL uses separate BodyDescriptors for the two kinds of
descriptor arrays, this caused a DCHECK failure when the deserializer
changes the map while the object is visited from the concurrent marking
thread. Fix this by disabling the corresponding checks.

That is because both stderr and the exit status are ignored. This CL

5326c4f86e [turboprop] Turnoff inlining for Turboprop based on compilation target
Turboprop adds a negative implication for inlining to disable inlining
with turboprop. When we add tiering up support from Turboprop, this
implication means we would no longer inline functions even with
Turbofan. This cl instead turns off inlining for turboprop compilations
so we still don't inline for Turboprop compilations but support
inlining for Turbofan.

5720d2056c [regexp] Add 'l' flag to force experimental engine
This commit adds the 'l' (linear) RegExp flag (as in e.g. /asdf|123/l)
that forces execution in linear time.  These regexps are handled by the
experimental engine.  If the experimental engine cannot handle the
pattern, an exception is thrown on creation of the regexp.

The commit also adds a new global V8 flag and changes an existing one:
* --enable-experimental-engine, which turns on recognition of the RegExp
  'l' flag.  Previously this flag also caused all supported regexps to
  be executed by the experimental engine; this is not the case anymore.
* --default-to-experimental-regexp-engine takes over the previous
  semantics of --enable-experimental-regexp-engine:  We execute all
  supported regexps with the experimental engine.

2288b1f638 [TurboFan] Provide concurrent access to feedback vector
This CL provides synchronized get/set to feedback vector slots.
The FeedbackNexus is set up to use order preserving reads when used
on the background thread, and a lock to ensure coherent read
of information for ICKinds with two slots. The main thread takes
the lock on sets.

This test provides patterns to be followed by concurrent TurboFan.

We don't yet access the FeedbackVector on the background thread.
This CL only makes it safe to do so. The next step will come when
the optimizing compiler begins to query the the vector from the
background thread. Currently, with --concurrent-inlining turned on
this is done in bytecode serialization on the main thread. Without
concurrent inlining, it's also done on the main thread, in both
cases using the FeedbackNexus.
