NameSectionKindCode::kFunction got shadowed by WasmCompilationResult::Kind::kFunction. NameSectionKindCode is not used often, so this CL just adds "Code" to all fields of this enum.

In Liftoff, the result of table.grow was smi-untagged and sign-extended to a ptr-sized value. However the result is typed as i32, so the upper 32 bits should be cleared on 64 bit platforms. In particular this is observable when the value is used as an index for a memory operand, which leads to the repro in the attached issue. Match the TF behavior by untagging the value as a 32-bit int.

Attempts to allocate memory pages inside the virtual memory cage are currently allowed to fall back to allocating them outside of the cage if necessary. When this will be forbidden in the future, these cases will turn into allocation failures. To estimate the frequency of such events, we now record the outcome of allocation attempts for memory inside the cage into UMA.

Similar optimization to the one for x64 at https://crrev.com/c/3154347. There is a change to VisitLoad, which should call GetEffectiveAddressMemoryOperand on the value node.

The CL provides a way for the embedder to hook in a special malloc-like allocator that will be used for zone allocations. An alternative approach would be to use weak functions with branches, checking whether the functions were available at link-time. Those branches could be optimized away with LTOs, so they would essentially be free. However, the weak function approach is not portable (e.g. there is no easy way to emulate it with msvc). The approach can be revisited if indirect call turns out to be expensive (e.g. on hardware with weak branch target predictors). The CL is a prerequisite for running PCScan in the renderer process.
