f84f45f9ca [turbofan] ARM64: Use zr for zeroing stack slots
When zeroing a floating point stack slot, store the zero register directly,
rather than storing zero moved to an FP register.

a400590761 [turbofan] Allow inlining into BytecodeGraphBuilder graph.
This is a first implementation of inlining into graphs that have been
created using the {BytecodeGraphBuilder}. Note that inlining sticks to
graphs of the same kind, we only ever inline AstGraph into AstGraph or
BytecodeGraph into BytecodeGraph, no mixed inlining.

3ff201906e [wasm] Write fuzzers for single wasm sections.
This CL adds fuzzers for the wasm module sections 'types', 'names',
'globals', 'imports', 'function signatures', 'memory', and 'data', one
fuzzer per section. No fuzzers are added for the other sections because
either there already exists a fuzzer (e.g. wasm-code), or there exist
inter-section dependencies.

To avoid introducing a bunch executables which would make compilation
with make slow, I introduce a single executable
'v8_simple_wasm_section_fuzzer' which calls the fuzzers mentioned above.
This executable is run by the trybots and ensures that the fuzzers
actually compile. For debugging I introduce commandline parameters which
allow to execute the specific fuzzers from 'v8_simple_wasm_section_fuzzer'.

c7d7ca361d [turbofan] Collect invocation counts and compute relative call frequencies.
Add a notion of "invocation count" to the baseline compilers, which
increment a special slot in the TypeFeedbackVector for each invocation
of a given function (the optimized code doesn't currently collect this
information).

Use this invocation count to relativize the call counts on the call
sites within the function, so that the inlining heuristic has a view
of relative importance of a call site rather than some absolute numbers
with unclear meaning for the current function. Also apply the call site
frequency as a factor to all frequencies in the inlinee by passing this
to the graph builders so that the importance of a call site in an
inlinee is relative to the topmost optimized function.

Note that all functions that neither have literals nor need type
feedback slots will share a single invocation count cell in the
canonical empty type feedback vector, so their invocation count is
meaningless, but that doesn't matter since we only use the invocation
count to relativize call counts within the function, which we only have
if we have at least one type feedback vector (the CallIC slot).

See the design document for additional details on this change:

0b8a69458e [turbofan] Call frequencies for JSCallFunction and JSCallConstruct.
Extract the call counts from the type feedback vector during graph
building (either via the AstGraphBuilder or the BytecodeGraphBuilder),
and put them onto the JSCallFunction and JSCallConstruct operators,
so that they work even across inlinine through .apply and .call (which
was previously hacked by creating a temporary type feedback vector
for those).

The next logic step will be to make those call counts into real
relative call frequencies (also during graph building), so that we
can make inlining decisions that make sense for the function being
optimized (where absolute values are misleading).

66dbc77eaf ValueDeserializer: Pretenure objects while deserializing large objects.
json-parser does the same thing. This drastically reduces GC cost when
deserializing objects large enough that multiple collections are likely
(since it saves the effort to move them to the old generation, when we
know that the objects we create will persist at least until the deserializer
finishes).

The threshold was chosen to match json-parser.

This patch reduces deserialization time on a large blob of JSON-y data
by approximately 30%.

3472b57a8f ValueSerializer: promote scheduled exception if the caller throws one.
v8::Isolate::Throw only schedules the exception; it is necessary to promote it
after invoking the delegate.

edb4d3151c Mark await expressions as caught or uncaught
Handle some examples of the "asynchronous case" by marking await expressions
as either caught or uncaught; in the caught case, this marks the Promise passed
in as having a catch predicted. The marking is done in AST numbering, which
chooses between two different runtime function calls based on catch prediction.

ee8ae932b8 [V8][Wasm] Removes references to finally in wasm.
The initial support for low level exception handling in Wasm will not
support finally blocks. This decision is taken for both simplicity (
handling finallys is not straightforward if we want try blocks to yield
values), and lack of good use case (clang++ does not need them.) They
may be added in the future once we understand the implications of
having them.
