Adds rust types to reserved names.

Fixes #1204

I considered sorting the (un)signed types properly, but I thought it wouldn't really matter.
Also, should we care about columns like "i32"?

I'd rather avoid speculatively doing this for all types, as there's no reason you couldn't just have a column called char. The only reason that bool is causing an issue is that it appears in the signature of a trait. I believe we can fix that by just changing impl_query_id! to use ::std::bool instead of bool, and not touch codegen at all

Hm... Actually ::std::bool doesn't work. I wonder if there even is a way to reference bool with an absolute path

[sgrif]

I've opened rust-lang/rust#44865 to see if we can get a better way to do this. In the short term I think we should add this to the crate root:

// Referenced by `impl_query_id!` to ensure we get the right type if users have
// a column called `bool`. This should be removed when the language lets us
// reference `bool` with an absolute path
#[doc(hidden)]
pub type RealBool = bool;

and change impl_query_id! to use $crate::RealBool instead of bool. We should also add tests for this. Simply adding a migration with a column that has the same name as each primitive should suffice. Your list is also missing str

I'm going to close this, as it's gotten out of date. I would still like to see the underlying issue fixed, but through the method I mentioned above rather than making these names reserved.
