Add string allocation fast path outside Windows
- On Linux, a microbenchmark is 140% faster with the portable fast path
- On Windows with the asm fast path, the microbenchmark was 300% faster than on Linux before, and is now 65% faster with the portable fast path
- On Windows, the portable fast path is 5% slower than the asm fast path
