* add `@compileLog(...)` builtin function - Helps debug code running at compile time - See #240 * fix crash when there is an error on the start value of a slice * add implicit cast from int and float types to int and float literals if the value is known at compile time * make array concatenation work with slices in addition to arrays and c string literals * fix compile error message for something not having field access * fix crash when `@setDebugSafety()` was called from a function being evaluated at compile-time * fix compile-time evaluation of overflow math builtins. * avoid debug safety panic handler in builtin.o and compiler_rt.o since we use no debug safety in these modules anyway * add compiler_rt functions for division on ARM - Closes #254 * move default panic handler to std.debug so users can call it manually * std.io.printf supports a width in the format specifier
