code_cache_map_ is used to store the serialized code that could be consumed in the subsequent runs. This is a std::map which is not thread safe. So protect this with mutex to avoid any race conditions when executing in multiple isolates in parallel.

The return type of stores is void according to the WebAssembly spec. In wasm-opcodes.h, however, the return type of stores was set to the value type. This CL changes the signature of stores, and fixes some issues which were caused because now there exist opcodes with a return count different to 1.

PIC code requires that full function address is available in t9 upon function entry. We disabled some optimizations that cause problems since they do not load t9 with full function address.

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.

Separates restoring iterability from sweeping a page. Since the set of pages where iterability needs to be restored is small, it is possible to wait and block for the task to finish if necessary. A follow up change can now remove the fragile logic for delaying unmapping of pages since it is guaranteed that no background task keeps a reference to a page for restoring iterability.

Add support for matching '(x & mask) == mask' when mask has a single bit set, and translate this into a tbnz instruction. This patch only does this for 32-bit operations, we can port it to 64-bit operations as a follow-up if we find matches. This transformation mostly touches the snapshot where we get ~120 hits. This pattern can also show up in JavaScript when introduced by the EffectControlLinearizer pass.

The existing object materialization in the deoptimizer has the following problems: - Objects do not necessarily verify during materialization (because during the depth first walk we might have inconsistent objects). - Stack can overflow (because we just materialize using recursive calls). - We generalize object fields. This CL re-implements the materialization algorithm to solve this problem. The new implementation creates the objects in two steps: 1. We allocate space for all the objects. In general, we allocate ByteArrays of the right size. For leaf objects that cannot participate in cycles, we build and initialize the materialized objects completely. For JS objects, we insert markers into the byte array at the positions where unboxed doubles are expected. 2. We initialize all the objects with the proper field values and change the map from the ByteArray map to the correct map. This requires some sync with the concurrent marker (Heap::NotifyObjectLayoutChange). When initializing the JS object fields, we make sure that we respect the unboxed double marker.

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.
