dearblue 1354ad96ec Avoid creating temporary objects with new_lit() in codegen.c
At the same time, the saving and restoration of unwanted object arenas was removed.
In addition, the common code to extend the pool that existed before has been grouped together and newly established as `lit_pool_extend()`.
Note that previously the variable `i` was updated at that time, but since it is the same as the value at the end of a `for` statement, it has been omitted.

The original catalyst was that `bin/mrbc` with the `MRB_WORD_BOXING` + not `MRB_BOXWORD_NO_FLOAT_TRUNCATE` configuration caused `bin/mrbtest` with the `MRB_NO_BOXING` configuration to fail.
Upon investigation, I concluded that avoiding the creation of temporary objects would prevent the truncation of floating point numbers.
Therefore, this patch also prevents the `rake test` from failing with the following configuration.

```console
% cat test_config.rb
bootstrap_mrbc = nil

MRuby::Build.new do |conf|
  conf.toolchain
  conf.enable_debug
  conf.enable_test
  conf.disable_presym
  conf.defines << %w(MRB_WORD_BOXING)
  #conf.defines << %w(MRB_WORDBOX_NO_FLOAT_TRUNCATE)
  gem core: "mruby-bin-mrbc"
  gem core: "mruby-kernel-ext"
  bootstrap_mrbc = File.join(conf.build_dir, "bin/mrbc")
end

MRuby::Build.new("nobox") do |conf|
  conf.toolchain
  conf.enable_debug
  conf.enable_test
  conf.defines << %(MRB_NO_BOXING)
  conf.mrbcfile = bootstrap_mrbc
  gem core: "mruby-kernel-ext"
end
```
