Details

(Whiteboard: [sp3])

The code we emit in the JITs to allocate objects and strings in the nursery is probably faster than what we do now in C++. It might be possible to carve out a faster C++ code path for the common case that can be fully inlined. This code is hot enough that it's worth trying.

NI jonco because we talked about this a bit, and this is potentially important for Speedometer.
