For section `.foo`, `InputBaseSection::{areRelocsRela,firstRelocation,numRelocation}` basically
encodes the information of `.rel[a].foo`. However, one uint32_t (the relocation section index)
suffices. See the implementation of `relsOrRelas`.

This change decreases sizeof(InputSection) from 184 to 176 on 64-bit Linux.
