Log:
Fix perf. of RCLASS_EXT_WRITABLE
FL_TEST -> FL_TEST_RAW
FL_SET -> FL_SET_RAW
I was seeing bad performance on the ruby-bench getivar-module benchmark
when using yjit. This was with other changes in a branch, but changes
totally unrelated to accessing ivars on a class or using boxes. The
change to RCLASS_PRIME_CLASSEXT_WRITABLE_P was the one that made the
difference, but I changed a couple of other FL_SET uses as well. This
change reduced the benchmark runs from 60ms to 40ms.
