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.

2ef68631cb stage2 now supports using stage1 as a backend for compiling zig code 
* move stage2.cpp code into zig0.cpp for simplicity
 * add -ftime-report and some more CLI options to stage2
 * stage2 compites the llvm cpu features string
 * classifyFileExt understands more file extensions
 * correction to generateBuiltinZigSource using the wrong allocator
   (thanks dbandstra!)
 * stage2 is now able to build hello.zig into hello.o using stage1 as a
   library however it fails linking due to missing compiler-rt
 * remove dead code
 * simplify zig0 builtin.zig source
 * fix not resolving builtin.zig source path causing duplicate imports
 * fix stage1.h not being valid C code
 * fix stage2.h not being valid C code
