For import wrappers, we add a special "callable" parameter as the last
parameter. This parameter is not set in the TurboFan graph but in the
code generator. Therefore this parameter has to be allocated in a
special register and cannot be lowered generically. With this CL we
detect in the CallDescriptor lowering if the last parameter is this
special "callable" parameter. If so, we preserve it in the lowered
CallDescriptor in the same register.

A benign datarace can occur between the array buffer tracker and
using an arraybuffer as an asm.js memory. The former reads the
{is_shared} bit, which should never change, and the latter writes
the {is_asmjs_memory} bit, but no other bits. Since these bits are
packed into a single word, TSAN reports a race.

Before running OOM on a wasm memory allocation, we trigger a GC, but
only in the isolate which allocates the new wasm memory. Hence if
multiple isolates are involved, we can run OOM anyway. This is a rare
