This patch updates the instruction selector and code generator to pad arguments
for arm64 and drop an even number of slots when dropping the arguments. It also
updates the builtins that handle arguments. These changes need to be made at
the same time.
It also adds some tests for forwarding varargs, as this was affected by the
builtin changes and the existing tests did not catch all issues.

There was an issue when the caller of a function with multiple returns
did not use all values which were returned over the stack. The caller
used only the used returns to calculate the offsets on the stack,
whereas the callee used all returns to calculate the offsets.
With this CL also the caller uses all returns to calculate the stack
offsets and thereby agrees again with the callee on the location of
all returns.
In addition I fixed an issue on x64: A quad word is reserved on the
stack frame to spill callee-saved FP registers, which is not pointer
size.

The interface of {WasmCompiledModule} currently mostly receives and
provides handles to the contained data. Other interfaces don't (see
{object-macros.h}.
This leads to performance and memory overhead for chained accesses like
{instance->compiled_module()->shared()->script()}, because intermediate
accessors allocate Handles for no reason. It also breaks the
constraints that lower-case accessors should be trivial to execute, but
allocating a handle is not trivial (should not be done in a loop if not
needed).
It also silences gcmole errors, as documented in
https://crrev.com/c/832268.

In a certain scenario streaming compilation got stuck and did never
finish. This CL fixes this issue.
Scenario:
* Streaming compilation starts
* The compilation tasks execute all compiation units in the working
queue and set the finished_ flag to true.
* New data arrives over streaming
* The compilation tasks compile so fast that the executed_units_ queue
gets full. The compilation tasks stop executing and wait for the
finisher task to restart them.
* The finisher task does not restart the compilation tasks because the
finished_ flag is set.
With this CL I remove the finished flag and instead look at the size
of the working queue directly.
In addition I added a test which does not actually reproduce this
scenario but seems good to have anyways.

The dispatcher is responsible for handling stores to lexical environment
variables and for storing directly to the JSGlobalObject. In the latter
case the dispatcher also ensures that JSGlobalProxy is provided as
a receiver if a setter function has to be called.
Unlike StoreIC the calling convention for the StoreGlobalIC does not include
receiver.

JS code may sometimes make calls to helper native functions that do not
provide any special stack layout besides the return address and frame pointer.
Currently the stack iterator bails out when it sees an unknown frame.
The patch allows the iterator to unwind stacks having such frames.

we move move top(). UpdateAllocationInfo is the correct place for this
rather than the callers of UpdateAllocationInfo.

Currently Page::ShrinkToHighWaterMark checks that there is only one
filler in the to-be-freed area at the end of the page. This does not
hold if an allocation observer is active.
We should instead check that the to-be-freed area does not contain
allocated objects and will not contain allocated objects:
1) Following chain of fillers we arrive at the end of the page.
2) The free list of the page is empty.
This patch also changes PagedSpace::ResetFreeList to evict free list
entries of each page, instead of just reseting the global free list.
It also removes invalidation of free list categories.
Now FreeList::EvictFreeListItems simply evicts free list entries without
invalidating free list categories.

The original CL introduced a test which uses a random number generator.
I disable the test for now, which is okay because this CL adds to a
work-in-progress feature anyways, and I will fix the problem in another
CL.
Original description:
Add the ability to return (multiple) return values on the stack:
- Extend stack frames with a new buffer region for return slots.
This region is located at the end of a caller's frame such that
its slots can be indexed as caller frame slots in a callee
(located beyond its parameters) and assigned return values.
- Adjust stack frame constructon and deconstruction accordingly.
- Extend linkage computation to support register plus stack returns.
- Reserve return slots in caller frame when respective calls occur.
- Introduce and generate architecture instructions ('peek') for
reading back results from return slots in the caller.
- Aggressive tests.
- Some minor clean-up.
So far, only ia32 and x64 are implemented.

This is a separation of the DFA Unicode Decoder from
https://chromium-review.googlesource.com/c/v8/v8/+/789560
I attempted to make the DFA's table a bit more explicit in this CL. Still, the
linter prevents me from letting me present the array as a "table" in source
code. For a better representation, please refer to
https://docs.google.com/spreadsheets/d/1L9STtkmWs-A7HdK5ZmZ-wPZ_VBjQ3-Jj_xN9c6_hLKA
- - - - -
Now for a big copy-paste from 789560:
Essentially, reworks a standard FSM (imagine an
array of structs) and flattens it out into a single-dimension array.
Using Table 3-7 of the Unicode 10.0.0 standard (page 126 of
http://www.unicode.org/versions/Unicode10.0.0/ch03.pdf), we can nicely
map all bytes into one of 12 character classes:
00. 0x00-0x7F
01. 0x80-0x8F (split from general continuation because this range is not
valid after a 0xF0 leading byte)
02. 0x90-0x9F (split from general continuation because this range is not
valid after a 0xE0 nor a 0xF4 leading byte)
03. 0xA0-0xBF (the rest of the continuation range)
04. 0xC0-0xC1, 0xF5-0xFF (the joined range of invalid bytes, notice this
includes 255 which we use as a known bad byte during hex-to-int
decoding)
05. 0xC2-0xDF (leading bytes which require any continuation byte
afterwards)
06. 0xE0 (leading byte which requires a 0xA0-0xBF afterwards then any
continuation byte after that)
07. 0xE1-0xEC, 0xEE-0xEF (leading bytes which requires any continuation
afterwards then any continuation byte after that)
08. 0xED (leading byte which requires a 0x80-0x9F afterwards then any
continuation byte after that)
09. 0xF1-F3 (leading bytes which requires any continuation byte
afterwards then any continuation byte then any continuation byte)
10. 0xF0 (leading bytes which requires a 0x90-0xBF afterwards then any
continuation byte then any continuation byte)
11. 0xF4 (leading bytes which requires a 0x80-0x8F afterwards then any
continuation byte then any continuation byte)
Note that 0xF0 and 0xF1-0xF3 were swapped so that fewer bytes were
needed to represent the transition state ("9, 10, 10, 10" vs.
"10, 9, 9, 9").
Using these 12 classes as "transitions", we can map from one state to
the next. Each state is defined as some multiple of 12, so that we're
always starting at the 0th column of each row of the FSM. From each
state, we add the transition and get a index of the new row the FSM is
entering.
If at any point we encounter a bad byte, the state + bad-byte-transition
is guaranteed to map us into the first row of the FSM (which contains no
valid exiting transitions).
The key differences from Björn's original (or his self-modified) DFA is
the "bad" state is now mapped to 0 (or the first row of the FSM) instead
of 12 (the second row). This saves ~50 bytes when gzipping, and also
speeds up determining if a string is properly encoded (see his sample
code at http://bjoern.hoehrmann.de/utf-8/decoder/dfa/#performance).
Finally, I've replace his ternary check with an array access, to make
the algorithm branchless. This places a requirement on the caller to 0
out the code point between successful decodings, which it could always
have done because it's already branching.

The previous code assumed that trap handling was a global concept, defined
by function trap_handler::UseTrapHandler(). This CL does the first step
in changing the decision to be specifiable at a module level.
Therefore trap_handler::UseTrapHandler() is replaced by
trap_handler::IsTrapHandlerEnabled(), and communicates if compilation
supports the use of trap handlers (but still allowing the use of
bounds checking on memory accesses).
It then refactors the classes ModuleEnv and WasmCompiledModule to have
a field "use_trap_handler" that specifies if traps should be used for
the memory accesses in the module being compiled.

This is to avoid calling AssembleTailCallBeforeGap and AssembleTailCallAfterGap
directly where possible (so making the tests less dependent on the code generator
interface when we're not directly testing it). It also makes sure that the
instruction we pass to AssembleTailCallBeforeGap and AssembleTailCallAfterGap is
indeed a tail call, with the immediate argument that specifies the stack delta.
This is to prepare for padding arguments for arm64 JSSP removal. We will need to
store padding in AssembleTailCallAfterGap, which will need the information from
a TailCall instruction.

Eventually we should migrate to new new-style callbacks which take Names
instead of Strings as first arguments everywhere. Internally we don't really
handler NamedPropertyCallbackXX differently from the newer
GenericNamedPropertyCallbackXX.

This patch normalizes the casing of hexadecimal digits in escape
sequences of the form `\xNN` and integer literals of the form
`0xNNNN`.
Previously, the V8 code base used an inconsistent mixture of uppercase
and lowercase.
Google’s C++ style guide uses uppercase in its examples:
https://google.github.io/styleguide/cppguide.html#Non-ASCII_Characters
Moreover, uppercase letters more clearly stand out from the lowercase
`x` (or `u`) characters at the start, as well as lowercase letters
elsewhere in strings.

Adds new API function to request code cache. Earlier code cache was
produced along with compile requests. This new API allows us to request
code cache after executing. Also adds support in the code serializer to
serialize after executing the script.

Original change's description:
> [objects] No longer create short external strings.
>
> This fixes String::MakeExternal() to bail out if the subject string
> doesn't fit a regular ExternalString, instead of creating a short
> external string. The observation here is that for short external strings
> the overhead of having to have the StringResource plus going to the
> runtime/C++ for each and every character access from JavaScript land
> is probably bigger than the anticipated benefits.
>
> If this turns out to be wrong and there's a real benefit, we should make
> use of ThinStrings instead of having a separate way to represent
> external strings.
