41a8d9c352 [base] Store AllocationPolicy object in TemplateHashMapImpl instance
... this will avoid the need to pass AllocationPolicy to every method
that can allocate/deallocate and allows to make deallocation method
implementation stateful.

The latter will also allow implementing accounting of deallocated zone
memory.

Adding one more field is generally fine because usually these hashmap
objects are allocated on the stack or inside other rarely-allocated
long-lived objects.
The only exception is Scope class. The Scope objects are created very
often during parsing and each of them has a VariableMap field.
The Scope object size issue will be addressed in a follow-up CL.

ebcc39d59a [tests] Fix parameter indices in test-code-stub-assembler
The cctests were wrong, since they access the first parameter using `Parameter(0)`. They should instead use `Parameter(1)`, since the index 0 is the receiver, and the receiver is set to be always the undefined object in `FunctionTester::Call`.

The reason it used to work is that the tests would set up an access to the stack with the wrong number of parameters, accessing only a stack suffix.

e72702454a [test] Skip huge-TypedArray test in stress_snapshot mode
The snapshot code assumes that the entire snapshot's length fits into
an int, which implies that it doesn't support individual objects that
are bigger than that. That's okay, because it isn't reachable from
user code, and embedders would notice at compile time when they run
into this limit. So we can just continue to skip the few regression
tests we have for huge TypedArrays in the stress_snapshot variant.

e15fcb6651 Reland "[heap] Avoid ParkedMutexGuard during allocation"
This is a reland of 273f4e42e3

Original change's description:
> [heap] Avoid ParkedMutexGuard during allocation
> 
> Since main thread allocation does not start incremental marking anymore
> while holding allocation_mutex_, background allocation does not need
> ParkedMutexGuard anymore to avoid deadlocks.
> 
> This also means background thread allocation isn't paused anymore to
> perform a GC, which already resulted in subtle bugs (e.g. in
> ExpandBackground with incremental marking). We also do not
> stop-the-world anymore while holding allocation_mutex_.

a90596329f [TurboProp] Add framework to pipeline.cc for a fast register allocator.
Adds basic framework to pipeline.cc to enable a seperate fast register
allocator for the TurboProp mid-tier. As part of this, common logic as
well as a base class for RegisterAllocationData is moved to a seperate
register-allocation.h header file. The current register allocator's
RegisterAllocationData is renamed to TopTierRegisterAllocationData, and
the former name is the new base class held in PipelineData.

c8679386bd [snapshot] enable mksnapshot usage to be displayed
Currently, when specifying '--help' with mksnapshot it will only
print the v8/d8 help message and options and then exit the process.
This means that the usage message from mksnapshot will never be
displayed.

This commit suggests adding an option to SetFlagsFromCommandLine that
can disable this printing and exiting. This allows mksnapshot to display
the usage and print the options after that.

While this works, it does seems a little strange that
SetFlagsFromCommandLine prints the help message and exits the process
but I'm probably missing some background details around this.

7c10560da2 [wasm-simd][arm64][arm] Fix v128.const
There is a sign-extension bug happening when packing 2 32-bit ints into
a 64-bit int. We are OR-ing int32_t with a uint64_t, so an integral
conversion converts int32_t to uint64_t, which is a sign extension, and
this gives unexpected results for a negative value:

    0x80000000 | uint64_t{0} -> 0xffffffff80000000

What we want is 0x0000000080000000.

Created a helper function to do this work of combining two uint32_t
into one uint64_t. The use of this function will also ensure that
if callers passed a int32_t, it would first be converted to a
uint32_t, and will not have this sign extension bug.

Sneaked a small regression test into the existing v128.const cctest,
and also cleanup the loop to reset `expected` array to 0.

2b873b94e9 [compiler] Don't serialize BytecodeArrayData's source_positions_
This CL adds functionality to read the source positions directly
from the JS heap rather than from serialized data.

In order to do this, we create a PersistentHandles container in the
OptimizedCompilationInfo which gets passed onto the JSHeapBroker. This
allows us to create the handles in the main thread and pass them safely
to the background thread.

In order to read safely from the background thread, we need a LocalHeap
which blocks the GC from running and potentially moving the handles.
This LocalHeap is created only when the JSHeapBroker has finalized
serializing and destroyed when retiring it.
