  [JSC] Unreviewed RISCV64 build fix

Fix the RISCV64 build of JavaScriptCore. In MacroAssemblerRISCV64, the
supportsCountPopulation() static function is added, returning false,
since the underlying RISC-V functions are only available with certain
extensions we currently can't hard-depend on. No-op templates are added
for two related count-population methods.
