CL 68490 reworked the way the panicmem function is exposed to the C mach expection catcher. However, //go:cgo_export_static isn't enough: the underlying assembly functions must not start with the middle dot. Without the middle dot, the panicmem function's exported name is not prefixed with its package; rename it to xx_cgo_panicmem to decrease the chance of a symbol name clash. Finally, mark the overridden C symbol weak to avoid duplicate symbol errors from the host linker. For the ios builders.
