New Language Features

Allow unions to be comparable if all the variants are comparable
Comparable unions allowed as map keys
Improve implicit selector expression inference rules with unions
Unified cond ? x : y and x if cond else y logic
Improve type inference system to allow &{} alongside &T{} in some cases
Change for in x..y behaviour to prevent the possibility of overflowing on maximum integer size and causing an infinite loop
Allow ..= alongside .. as a "full range" operator (..= will probably replace .. for ranges)
Remove @(static) for global variables
Add @(link_section=<string>) for global variables
Add intrinsics: mem_zero, mem_copy, mem_copy_non_overlapping, sqrt, ptr_offset, ptr_sub

Tokenize ++ and -- as tokens but disallow them in the parser, and give better error messages for they are used as operators/statements
Add -verbose-errors
Improved parsing error messages
EXPERIMENTAL -use-separate-modules support (useful for speeding up code generation in development builds)
