avoid calling into stage1 backend when AstGen fails
The motivation for this commit is that there exists source files which produce ast-check errors, but crash stage1 or otherwise trigger stage1 bugs. Previously to this commit, Zig would run AstGen, collect the compile errors, run stage1, report stage1 compile errors and exit if any, and then report AstGen compile errors. The main change in this commit is to report AstGen errors prior to invoking stage1, and in fact if any AstGen errors occur, do not invoke stage1 at all. This caused most of the compile error tests to fail due to things such as unused local variables and mismatched stage1/stage2 error messages. It was taking a long time to update the test cases one-by-one, so I took this opportunity to unify the stage1 and stage2 testing harness, specifically with regards to compile errors. In this way we can start keeping track of which tests pass for 1, 2, or both. `zig build test-compile-errors` no longer works; it is now integrated into `zig build test-stage2`. This is one step closer to executing compile error tests in parallel; in fact the ThreadPool object is already in scope. There are some cases where the stage1 compile errors were actually better; those are left failing in this commit, to be addressed in a follow-up commit. Other changes in this commit: * build.zig: improve support for -Dstage1 used with the test step. * AstGen: minor cosmetic changes to error messages. * stage2: add -fstage1 and -fno-stage1 flags. This now allows one to download a binary of the zig compiler and use the llvm backend of self-hosted. This was also needed for hooking up the test harness. However, I realized that stage1 calls exit() and also has memory leaks, so had to complicate the test harness by not using this flag after all and instead invoking as a child process. - These CLI flags will disappear once we start shipping the self-hosted compiler as the main compiler. Until then, they can be used to try out the work-in-progress stage2. * stage2: select the LLVM backend by default for release modes, as long as the target architecture is supported by LLVM. * test harness: support setting the optimize mode
