erb.rb: Generate static string with opt_str_uminus
to skip object allocation for static string.
We can't always enable frozen_string_literal pragma because we can't
freeze string literals embedded by user for backward compatibility.
So we need to use fstring for each static string.
Since adding ".freeze" to string literals in #content_dump is slow
on compiling, I used unary "-" operator instead.
benchmark/bm_app_erb_render.rb: Added rendering-only benchmark to
test rendering performance on production environment.
This benchmark is created to reproduce the behavior on Sinatra (Tilt).
Thus it doesn't use ERB#result to skip parsing compiled code.
It doesn't use ERB#def_method too to regard `title` and `content` as
local variables. If we use #def_method, `title` and `content` needs
to be method call. I wanted to avoid it.
This patch's benchmark results is:
* Before
app_erb_render 1.250
app_erb 0.704
* After
app_erb_render 1.066
app_erb 0.686
This patch optimizes rendering performance (app_erb_render) without
spoiling (total of rendering +) compiling performance (app_erb).
