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

Compiler Improvements

• 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)
• Correct SysV ABI edge cases
• Array arithmetic code generation improvements for small arrays
