String.prototype.indexOf must clamp the `position` argument as per
step:
7. Let start be the result of clamping pos between 0 and len.
Source: tc39.es/ecma262/#sec-string.prototype.indexof
Previously, this was done in the StringIndexOf builtin, but the recent
refactor changed builtin implementations to match the spec more
closely (i.e. to clamp in String.prototype.indexOf, not
StringIndexOf). This means we now have to clamp in
JSCallReducer::ReduceStringPrototypeIndexOf.

This CL is part of a series that implements Turbofan support for
property accesses satisfying the following conditions:
1. The holder is a dictionary mode object.
2. The holder is a prototype.
3. The access is a load.
This feature will only be enabled if the build flag
v8_dict_property_const_tracking is set.
This particular CL modifies existing mjsunit tests whose assumptions
don't hold if v8_dict_property_const_tracking is enabled. This is
done by adding special handling for the case that
%IsDictPropertyConstTrackingEnabled() holds.

With support for exception handling, the stack overflow exception can be

It could happen (e.g. with --stress-background-compile) that the main
thread blocks for a background thread but the background thread requests
a GC from the main thread. This would result in a deadlock. Avoid this
by parking the main thread for potentially blocking operations and allow
allocations while the main thread is parked.
This CL introduces new states for the main thread: CollectionRequested
and ParkedCollectionRequested. These states will force Safepoint(),
Park() and Unpark() on the main thread into slow paths. The slow path
can then perform a GC on the main thread - right before parking or after
the main thread got unparked.

The build time flag v8_dict_mode_prototypes is ill-named, because it
does not control whether properties are kept in dictionary mode (this
is done by the v8_dict_property_const_tracking flag), but instead it
controls if SwissNameDictionary or NameDictionary is used as the
property backing store for all dictionary mode objects.
This CL renames the flag and updates its description.

Don't switch to the catch state if it is never reached.
Also steal the catch state instead of splitting it since it cannot be
used after a delegate instruction.

In inspector-task.cc, the frontend and backend runners are explicitly
joined before going out-of-scope. On POSIX platforms, calling
pthread_join() on a thread that has already been joined has undefined
behavior. For example, under the musl C runtime library, a successful
call to pthread_join() will unmap the pthread_t thread information
region, and calling pthread_join() again will result in SIGSEGV.

AddImmediate ends up pushing repeated immediates very often
unecessarily. Add support for Int64 immediates being inlined into
InstructionOperand if they fit into the payload (which is almost always
the case). Also add a seperate rpo_immediate vector for RPO numbers to
avoid having to add them to the immediates_ vector multiple times.
Ideally the RPO values would also be inlined, however JumpThreading
needs to patch RPO targets throughout the instruction stream, so we
need an indirection.

This CL enables proper testing for the CSA/Torque implementation of
SwissNameDictionary. This is done by changing the implementation of
test_swiss_hash_table::CSATestRunner.
This is the last CL of this series and concludes the CSA/Torque
implementation of SwissNameDictionary.

We already skip all tests on no-simd-sse builds, in effect not testing
scalar lowering. So, remove explicit tests for scalar lowering for all
other build configurations.
