bbff6bd675 Eventloop: Enable basic event loop test, fixed by previous commit 
Closes #4922

0eed7ec9d5 Eventloop: Fix deadlock in linux event loop implementation 
A simple empty main with evented-io would not quit, because some
threads were still waiting to be resumed (by the os). The os.write to
the eventfd only wakes up one thread and thus there are multiple writes
needed to wake up all the other threads.

800a4a6ceb eliminate dependency of libzigcpp.a on libzigstage1.a 
This allows us to create a build of self-hosted with LLVM extensions
enabled but without the stage1 backend.

c2b1cd7c45 stage2: implement zig build 
As part of this:

 * add std.process.cleanExit. closes #6395
   - use it in several places
 * adjust the alignment of text in `zig build --help` menu
 * Cache: support the concept of "unhit" so that we properly keep track
   of the cache when we find out using the secondary hash that the cache
   "hit" was actually a miss. Use this to fix false negatives of caching
   of stage1 build artifacts.
 * fix not deleting the symlink hash for stage1 build artifacts causing
   false positives.
 * implement support for Package arguments in stage1 build artifacts
 * update and add missing usage text
 * add --override-lib-dir and --enable-cache CLI options
   - `--enable-cache` takes the place of `--cache on`
 * CLI supports -femit-bin=foo combined with --enable-cache to do an
   "update file" operation. --enable-cache without that argument
   will build the output into a cache directory and then print the path
   to stdout (matching master branch behavior).
 * errors surfacing from main() now print "error: Foo" instead of
   "error: error.Foo".

250664bea4 build runner: allow for a bit longer -D options 
so they can display in the --help menu without getting squished.

58ee5f4e61 std: Fix metadata corruption in HeapAllocator 
HeapAllocator stores the pointer returned by HeapAlloc right after the
data block and, after the recent allocator refactoring, the space for
this pointer was not taken into account in the calculation of the final
block size.

Fixes #5830

4bc1b7a7ac Fix io_uring_sqe to use the names of the first member of each union 
Now we're really future-proof... no more `opflags` creeping in.

When anonymous unions land, we can start using `accept_flags` etc.

Until then, code using this struct won't break when the kernel adds features.
