AstGen: disallow leading zeroes in int literals and int types
...
This makes `0123` and `u0123` etc. illegal.
I'm now confident that this is a good change because
I actually caught two C header translation mistakes in `haiku.zig` with this.
Clearly, `0123` being octal in C (TIL) can cause confusion, and we make this easier to read by
requiring `0o` as the prefix and now also disallowing leading zeroes in integers.
For consistency and because it looks weird, we disallow it for integer types too (e.g. `u0123`).

test-cases: remove failing test
...
This causes a stack overflow in a debug build of stage3 unfortunately. I
will open an issue to track this test coverage, which we absolutely
should get working - users of the compiler should get a compile error,
not a segfault if they hit the default branch quota from abusing
recursive inline functions.
Note that the problem does not occur in a release build of stage3
which has significantly reduced stack usage.
On Linux, I tried bumping up the stack size from 32 MiB to 64 MiB and it
did not solve the problem. I'm not sure why not. It seems like it should
be fine.
Note that we also have a problem of running test-cases in multi-threaded
mode which is currently the default. Currently Zig threads are spawned
with 16 MiB stack space.
