Due to differences in compiler versions and optimization levels, std::floor treats snan differently, as does std::ceil and std::trunc. So the implementation of some instructions is sometimes inconsistent with the physical machine. We add extra processing to them. Besides, fix Loong64Debugger::Debug error in simulator, IsTrap returns true only if break is encountered.

Instead of invoking both the generational and marking barrier explicitly, we can just invoke the combined barrier which does both for us. Also we simply use the full write barrier for all writes in the deserializer. While we could avoid the generational barrier in a few cases, this only costs us a single predictable untaken branch without an additional load.

Disable --always-use-string-forwarding-table when --shared-string-table is set. With --shared-string-table we can have parallel GCs in multiple client isolates. With --always-use-string-forwarding-table we can have young generation strings in the forwarding table, requiring table updates when the string gets promoted. This is not supported for parallel GCs.

Seth Brenith authored
My previous change https://crrev.com/c/3597106 led to some performance regressions in time spent on parsing and compilation. Those regressions might be due to increasing the reuse of old top-level SharedFunctionInfos. If the top-level SFI is old enough that its bytecode can be flushed, then perhaps other SFIs within the script have already been flushed. In that case, discarding information from a background compilation or code cache deserialization could be harmful.
