This code has nothing to do with the ISA's registers, it's about the format of ELF relocations. As such, __SIZEOF_LONG__, being a language / ABI-level property, is a more appropriate constant to use. This also makes it easier to support CHERI, where general-purpose registers are extended to be capabilities, not just integers, and so the register size is not the same as the machine word size. This also happens to make it more correct for RV64ILP32, where the registers are 64-bit integers but the ABI is 32-bit (both for long and for the ELF format), though properly supporting that ABI is not part of the motivation here, just a consequence of improving the code for CHERI.
