Takashi Kokubun ab4379e086 Refactor RB_SPECIAL_CONST_P (#6759) ... Since https://github.com/ruby/ruby/pull/6599, RUBY_IMMEDIATE_MASK also overlaps RUBY_Qnil. Now RB_SPECIAL_CONST_P seems confusing since both RB_IMMEDIATE_P and RB_TEST check for RUBY_Qnil while we only need to check RUBY_Qnil besides RUBY_IMMEDIATE_MASK. I'd like to make this change to make it less confusing. I confirmed that this doesn't change the number of instructions used for the RUBY_Qfalse check on Linux x86_64 GCC and macOS arm64 Clang.		2022-11-17 17:55:24 -08:00
