i32 comparisons often compare against constants, in order to implement conditional branches. This CL optimizes such code by not loading the constant into a register first, but directly emitting the comparison. The code is shared for implementing {if} and {br_if} (and thereby makes those two methods more readable).

This bailout applies only when young generation is disabled. Otherwise, getting the caged heap is required and the global load bailout becomes redundant.

We should cancel tasks before we destroy objects like the string table from the isolate. So far our concurrent tasks didn't interact with the isolate much, but we now have tasks that can e.g. access the heap concurrently. While this is not strictly necessary at the moment, I want to see whether there might be problems with that approach. In the future this order will be required e.g. for baseline batch compilation tasks.

Previously it generates a mvoq+pinsrq, now it generates a single punpcklqdq. punpcklqdq is smaller in code size, and also faster on most arch (latency 1, rthroughput of 1, 1 uop, uses 1 port) than pinsrq (latency 2, 2 uop, uses 2 port) (from https://uops.info/table.html) punpcklqdq is mean to work on int domain, and although we can't be certain what v128.const will be used for, the movq is considered an integer domain instruction, so we can avoid unnecessary transitions by using punpcklqdq (instead of movddup, which is similar in perf and code size).

This CL exposes the size of the virtual memory cage to the embedder through V8::GetVirtualMemoryCageSizeInBytes(). This will for example be useful to collect metrics about the cage reservation, such as how frequently it fails, in the future. While collecting these metrics directly in V8 would also be possible, it would require access to an Isolate, which is not yet available when the cage is initialized. As such, it is easier to enable the embedder to collect these metrics.
