[patch] Hide the stub created for MO_ExternalSymbol too.

I noticed that given
declare void @llvm.memset.p0i8.i32(i8* nocapture, i8, i32, i32, i1)
declare void @foo()
define void @bar() {
call void @foo()
call void @llvm.memset.p0i8.i32(i8* null, i8 0, i32 188, i32 1, i1 false)
ret void
}
We produce for 32 bit mach-o:
L_foo$stub:
.indirect_symbol _foo
.ascii "\364\364\364\364\364"
_memset$stub:
.indirect_symbol _memset
.ascii "\364\364\364\364\364"
I.E., for foo we hide the stub, but for memset we do not. This is
almost certainly a bug since from the linker perspective it shouldn't
matter if the undefined reference was created in LLVM's codegen or
not.
The attached patch fixes it.
Cheers,
Rafael
