A -Wunused-parameter warning was introduced by patch rG7f0244afa828 <https://reviews.llvm.org/rG7f0244afa828e0ef725a3f951304577090495713> [libc++abi] NFC: adding a new parameter base to functions for calculating… (authored by xingxue). The unused parameter `base` will be used in a follow-on patch D101298 <https://reviews.llvm.org/D101298>. This patch is to avoid the warning before D101298 <https://reviews.llvm.org/D101298> is landed.
