Use standard `for` and `if` with non-reactive variables

[benmccann]

Describe the problem

If you do an {#if} check with a const then a $.if statement is output

Here's a silly REPL containing an {#if} and {#each} operating on a const:

Describe the proposed solution

Using just a standard if instead would result in smaller and faster code. The same holds for $.each vs for

Also, for very simple apps it might avoid pulling in functions like each and reconcile resulting in a smaller runtime. My site is actually simple enough that the only data I have is hard coded in the app and would actually fall into this category

nice to have
