std.debug.assert: remove special case for test builds
Previously, std.debug.assert would `@panic` in test builds,
if the assertion failed. Now, it's always `unreachable`.

This makes release mode test builds more accurately test
the actual code that will be run.

However this requires tests to call `std.testing.expect`
rather than `std.debug.assert` to make sure output is correct.

Here is the explanation of when to use either one, copied from
the assert doc comments:

Inside a test block, it is best to use the `std.testing` module
rather than assert, because assert may not detect a test failure
in ReleaseFast and ReleaseSafe mode. Outside of a test block, assert
is the correct function to use.

0e6c18c820 Remove StrLitKind enum
I was looking at the tokenizer specifically fn testTokenize and the
this statement looked odd:

  if (@TagType(Token.Id)(token.id) != @TagType(Token.Id)(expected_token_id)) {

I then saw the TODO and thought I'd remove StrLitKind figuring that
would make testTokenize simpler. It did so I thought I'd prepare this PR.

The tests are still working and stage2 zig seems to work, it compiles and
I was able to use the fmt command.

f06bce5dda introduce [*] for unknown length pointers
See #770

Currently it does not have any different behavior than `*`
but it is now recommended to use `[*]` for unknown length
pointers to be future-proof.

Instead of [ * ] being separate tokens as the proposal
suggested, this commit implements `[*]` as a single token.

fcbb7426fa use * for pointer type instead of &
See #770

To help automatically translate code, see the
zig-fmt-pointer-reform-2 branch.

This will convert all & into *. Due to the syntax
ambiguity (which is why we are making this change),
even address-of & will turn into *, so you'll have
to manually fix thes instances. You will be guaranteed
to get compile errors for them - expected 'type', found 'foo'

779247ba11 std.zig Major Refactor
* parser now parses expression like the C++ compiler does
* This makes initializers work
* Added control flow expression (only return is parsed)
* Added catch parsing (It doesn't quite work)
* The parse can now specify states as optional.
  * The parse will roll back on error if states are optional
  * This can be overriden by State.Required
