Improvements in the language

• -skip-unused is now on by default resulting in much smaller cgen and binaries. 70% reduction for hello world.
• -parallel-cc for speeding up -prod and -cc clang/gcc compilation by up to 14 times!
• C functions no longer need to be manually defined. An #include "foo.c" is enough (behind -experimental for now).
• Fixed arrays now have .index .any .all .map .sort .sorted methods
• Remove inline sum types completely

• Optimize literal string comparison (match, in and ==) (#22643)
• Allow map[k]()? and map[k]()() (#22740)
• Add selector option unwrapping inside if tree.root != none { (#22895)
