merge revision(s) 1fac99afdae2671a9ca86bead5bde4d0e2eff1b4: [Backport #18030]
skip marking for uninitialized imemo_env.
RUBY_INTERNAL_EVENT_NEWOBJ can expose uninitialized imemo_env
objects and marking it will cause critical error. This patch
skips marking on uninitialized imemo_env.
See: http://rubyci.s3.amazonaws.com/centos7/ruby-master/log/20210329T183003Z.fail.html.gz
