We can obtain the verbatim source code of Primitive.cexpr!. Why not
paste that content into the JITed program.

This changeset changes for instance Integer#integer? from:
== disasm: #<ISeq:to_i@<internal:integer>:66 (66,2)-(69,5)> (catch: FALSE)
0000 opt_invokebuiltin_delegate_leave <builtin!_bi7/0>, 0 (68)[LiCa]
0003 leave (69)[Re]
to:
== disasm: #<ISeq:to_i@<internal:integer>:66 (66,2)-(69,5)> (catch: FALSE)
0000 putself (68)[LiCa]
0001 leave (69)[Re]
which is of course faster.

[Feature #15589]

A prerequisite to fix https://bugs.ruby-lang.org/issues/15589 with JIT.
This commit alone doesn't make a significant difference yet, but I thought
this commit should be committed independently.
This method override was discussed in [Misc #16961].
