compiler_rt: refactor __mulodi2 and __muloti2 to get __mulosi2 - use comptime instead of 2 identical implementations - tests: port missing tests and link to archived llvm-mirror release 80 See #1290

const mulo = @import("mulo.zig");
std.debug.assert: remove special case for test builds Previously, std.debug.assert would `@panic` in test builds, if the assertion failed. Now, it's always `unreachable`. This makes release mode test builds more accurately test the actual code that will be run. However this requires tests to call `std.testing.expect` rather than `std.debug.assert` to make sure output is correct. Here is the explanation of when to use either one, copied from the assert doc comments: Inside a test block, it is best to use the `std.testing` module rather than assert, because assert may not detect a test failure in ReleaseFast and ReleaseSafe mode. Outside of a test block, assert is the correct function to use. closes #1304
