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

stage2: caching system integration & Module/Compilation splitting * update to the new cache hash API * std.Target defaultVersionRange moves to std.Target.Os.Tag * std.Target.Os gains getVersionRange which returns a tagged union * start the process of splitting Module into Compilation and "zig module". - The parts of Module having to do with only compiling zig code are extracted into ZigModule.zig. - Next step is to rename Module to Compilation. - After that rename ZigModule back to Module. * implement proper cache hash usage when compiling C objects, and properly manage the file lock of the build artifacts. * make versions optional to match recent changes to master branch. * proper cache hash integration for compiling zig code * proper cache hash integration for linking even when not compiling zig code. * ELF LLD linking integrates with the caching system. A comment from the source code: Here we want to determine whether we can save time by not invoking LLD when the output is unchanged. None of the linker options or the object files that are being linked are in the hash that namespaces the directory we are outputting to. Therefore, we must hash those now, and the resulting digest will form the "id" of the linking job we are about to perform. After a successful link, we store the id in the metadata of a symlink named "id.txt" in the artifact directory. So, now, we check if this symlink exists, and if it matches our digest. If so, we can skip linking. Otherwise, we proceed with invoking LLD. * implement disable_c_depfile option * add tracy to a few more functions

// Self-hosted has differing levels of support for various architectures. For now we pass explicit
// target parameters to each test case. At some point we will take this to the next level and have
// a set of targets that all test cases run on unless specifically overridden. For now, each test
// case applies to only the specified target.
