• checker: minimise the amount of string interpolation inside selector_expr
• builtin: remove string.clone() calls, in the most common case of interpolating strings (with no uppercasing or padding)
• v.ast: use != 0 instead of > 0, for commonly used methods like Type.has_flag() etc
• v.ast: eliminate array_get calls from Table.final_sym and Table.sym (make profiling data more useful)
• cgen: reduce interpolations in Gen.string_inter_literal
• cgen: small optimisation of frequently called cescape_nonascii
• v.util: check more strictly for a valid input in util.tabs/1

The RAM usage of the compiler is improved a bit, as well as the performance of mainly the checker:

Excellent work. 🥇
