Cherry Mui 9c7f0b1ccd cmd/link: mangle symbol ABI name for linker-generated symbols
The ABI mangling code skips symbols that are not loaded from Go
objects. Usually that is fine, as other symbols don't need name
mangling. But trampolines are linker generated and have the same
symbol version (ABI) as the underlying symbol. We need to avoid
symbol name collisions for trampolines, such as a trampoline to
f<ABI0> and a trampoline to f<ABIInternal>. We could explicitly
incorportate the ABI into the trampoline name. But as we already
have the name mangling scheme we could just use that.

The original code excludes external symbols probably because
symbols from C object don't need mangling. But a C symbol and a
Go symbol shouldn't have same name, and so the condition won't
apply.

Also exclude static symbols as they don't need mangling.
