There are some bugs on LTO and unused vars elimination, but in this testcase we
end up with:
main:
.LFB2:
subq$8, %rsp
.LCFI0:
movly(%rip), %esi
movl$.LC0, %edi
xorl

What I meant was that -ffunction-sections -fdata-sections and then
-Wl,--gc-sections to remove the unused variables/functions.

I think this optimization is up to the linker as the variables are marked as
hidden and not marked as local to the Translational unit.
