Optimizing Build Output

[chadhietala]

Right now Glimmer is bigger than it needs to be here are some known things to drive down the size:

• [ ] Create Feature Flag for stripping out DOM API fixes
• [ ] Babel helpers should not be inlined and repeated
• [ ] Make SVG black listing a debug time thing and strip from prod builds
• [ ] Support Targets (output is pretty fat from just compiling)
• [ ] Fix default args (has poor compilation)
• [ ] Make STATEMENT, APPEND and EXPRESSION functions tree shake-able (we can generate a file at build time that imports just the functionality needed by the runtime)
• [ ] We likely need something like Closure Compiler to do inlining and constant folding
• [ ] Investigate re-writing Enum compilation

Is this still relevant?
