While I was thinking about how isync isn't suitable for a memory fence, I
noticed we have no tests that it operates correctly to allow executing
modified instructions (e.g. JIT compilers), so I wrote one. Feel free to
move to a more appropriate location.
I tried to make as standalone as possible, yet still running on ppc64le
linux so it can be easily tested on a power9 cpu.
I spent quite a few hours trying to get a elf section to be both writable
and executable, was led down the wrong path of trying to use -Wl,-N and
finally figured out to use objcopy to edit the section flags.
