Jim Huang 256eb97849 Avoid unnecessary symbol exposure with ELF-based systems ...

GCC's default visibility is "public" but can be changed to
"hidden" with the argument "-fvisibility=hidden".

Tested with x86_64 / Ubuntu Linux 18.04 LTS:

[before]
$ nm -g -C libmimalloc.so | grep "T " | wc -l
142

[after]
$ nm -g -C libmimalloc.so | grep "T " | wc -l
93

This patch does not change the build on macOS.
