[DYNAREC] BOX64_DYNAREC_STRONGMEM tuning for libjvm
Hi,

The weak memory model architectures[1] reproduced less memory barrier related issue after tuning `BOX64_DYNAREC_STRONGMEM` to bigger one:

| BOX64_DYNAREC_STRONGMEM | SPECjvm2008[2] derby Reproduced SIGSEGV (run 10 times) smaller is better |
| ------------------------------------------------ | ------------------------------------------------------------------------------------------------------- |
| 1 | 80% |
| 3 | 20% |

So is it OK tuning `BOX64_DYNAREC_STRONGMEM` to bigger one for libjvm?
