Add error codes for libsyntax_ext
I intend to add error codes for `libsyntax_ext` as well. However, they cannot be used at stage 0 directly so I thought it might be possible to enable them at the stage 1 only so we can have access to the macros. However, the error code registration seems to not work this way. Currently I get the following error:
```
error: used diagnostic code E0660 not registered
--> libsyntax_ext/asm.rs:93:25
|
93 | span_err!(cx, sp, E0660, "malformed inline assembly");
| ^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^
|
= note: this error originates in a macro outside of the current crate (in Nightly builds, run with -Z external-macro-backtrace for more info)
error: used diagnostic code E0661 not registered
--> libsyntax_ext/asm.rs:151:33
|
151 | / span_err!(cx, sp, E0661,
152 | | "output operand constraint lacks '=' or '+'");
| |________________________________________________________________________________________^
|
= note: this error originates in a macro outside of the current crate (in Nightly builds, run with -Z external-macro-backtrace for more info)
error: aborting due to 2 previous errors
error: Could not compile `syntax_ext`.
```
If anyone has an idea, I'd gladly take it. I'm trying to figure this out on my side as well. I also opened this PR to know if it was worth it to continue (maybe we don't want this?).
Anyway, any answer for both questions is very welcome!

The syntax crate contains those things concerned purely with syntax
– that is, the AST ("abstract syntax tree"), parser, pretty-printer,
lexer, macro expander, and utilities for traversing ASTs.
For more information about how these things work in rustc, see the rustc guide:
