cdc8d9a5ec [TurboProp] Avoid marking the output of a call live in its catch handler
The output of a call won't be live if an exception is thrown while the
call is on the stack and we unwind to a catch handler.

cb802efb04 cppgc: Add TraceStrongly to Visitor
Align the library with the current blink implementation.
TraceStrongly takes a WeakMember and strongifies it so that the
referenced objects is retained.
This is used in blink during tracing of some weak collections.

de914c7507 Reland "[compiler, heap] Create LocalHeap outside of ExecuteJob"
This is a reland of 44708a5b6f

Original change's description:
> [compiler, heap] Create LocalHeap outside of ExecuteJob
>
> Create LocalHeap directly in the Task or in GetOptimizedCodeNow and
> pass its reference as argument to ExecuteJob. This allows us to create
> LocalHeap differently for the main and background thread, e.g. by
> passing an additional argument to the constructor in the future.
> It will be required in the future anyways when the main thread will
> have its own LocalHeap/LocalIsolate.
>
> Extending the scope of LocalHeap, also made
> HandleBase::IsDereferenceAllowed more precise and uncovered two
> potential issues: heap accesses in
> OptimizingCompileDispatcher::CompileNext and PipelineImpl::AssembleCode
> with --code-comments.
>
> LocalHeap can now be created in the parked state. Also fixed a data
> race with LocalHeap's destructor publishing write barrier entries
> without holding the lock.

7a9f2a4687 [snapshot] Dedicated code start symbol for sampling profiler
The UMA sampling profiler prefers unique symbol addresses, otherwise
disambiguation is fairly arbitrary (lexicographic).

To this end, introduce a dedicated symbol v8_code_start_for_profiler_
at a unique address (i.e. no other symbol is located at this address).

d028220c86 [wasm] Include prefix byte in length of bytes read
read_prefixed_byte is used mostly to read an entire prefixed opcode, it
writes the number of bytes of the opcode index (without prefix byte) to
the out param length. Change it so it writes the total number of bytes
(including the prefix byte), as that is what most callers want (they add
1 after calling read_prefixed_byte).

1aa7e19720 Implement parsing of empty import assertion clause
This is the first change in the process of implementing import
assertions per https://tc39.es/proposal-import-assertions/.

This CR adds support for the empty form of the AssertClause.

Also added is a --harmony-import-assertions flag to enable/disable
import assertions.  For now, the feature is off by default.

The next change will enable the parser to handle a non-empty list
of AssertEntries.

ebcff9e131 [wasm] Read prefixed opcodes as u32v
Prefixed opcodes have a 1 byte prefix, followed by LEB-encoded u32. This
changes all prefixed opcodes (gc, numeric, atomic), to that. (Simd was
already so.)

We can clean up read_prefix_opcode to return the total number of bytes,
1 byte prefix + leb encoded, that will be in a future patch.

13436edce2 [TurboProp] Handle allocation of phis which are never used
In certain situations a phi might not be used by later code, and so
is neither spilled nor has a register allocated to it. Handle this
by removing the incorrect DCHECK.

679a97093d [TurboProp] Avoid spills when merging blocks by adding gap moves.
When merging blocks in the mid-tier register allocator, try to avoid
spilling registers if we can instead introduce a gap move to move the
register choosen to hold a virtual register to the register that is
holding that virtual register in the successor block. This gives
around 1.5% speedup on Octane.

10dbddd1e8 [wasm] Fix stepping from a non-breakable position
... at function start. Otherwise we run into a position mismatch:
In a non-flooded function, we add the function-entry breakpoint (for
"hook on function call") with the position of the first opcode.
In the flooded function though, we skip that special breakpoint because
we will stop at the first instruction anyway. But then the first
instruction is non-breakable, so we don't actually emit a breakpoint for
it.
Hence during OSR we do not find a corresponding position in the new
code.

This CL fixes this by postponing the function-entry breakpoint until the
first breakable opcode is found, and only emits it if that position does
not have a breakpoint anyway.
This way, we can also move the handling for function-entry breakpoints
from {StartFunctionBody} to {EmitDebuggingInfo}, where it fits much
better.

44708a5b6f [compiler, heap] Create LocalHeap outside of ExecuteJob
Create LocalHeap directly in the Task or in GetOptimizedCodeNow and
pass its reference as argument to ExecuteJob. This allows us to create
LocalHeap differently for the main and background thread, e.g. by
passing an additional argument to the constructor in the future.
It will be required in the future anyways when the main thread will
have its own LocalHeap/LocalIsolate.

Extending the scope of LocalHeap, also made
HandleBase::IsDereferenceAllowed more precise and uncovered two
potential issues: heap accesses in
OptimizingCompileDispatcher::CompileNext and PipelineImpl::AssembleCode
with --code-comments.

LocalHeap can now be created in the parked state. Also fixed a data
race with LocalHeap's destructor publishing write barrier entries
without holding the lock.

944dad59c8 [x64] Add movlps and movhps to assembler
These instructions will be used for prototyping Wasm SIMD's store lane
later on, separated the implementation for assembler and disassembler
into this patch to make things smaller.

Curiously, movhps and movlhps seems to have the same encoding, 0f 16, so
I'm not sure not sure how to differentiate them in the disassembler
besides using the mod field, since movlhps only takes xmm registers,
whereas movhps always take 1 operand.
