Type aliases cannot be used in parametric instantiations

[mikex-oss]

Describe the bug DSLX parser stumbles on type aliases in parametric instantiations. It seems to parse the expression as multiple comparison operators after reaching the > after the parametric value when the type is not a builtin type.

To Reproduce Steps to reproduce the behavior:

1. Compile below snippet:

type foo_t = bits[32];

fn f<N:u32>(x: u32) -> u32 { N + x }
fn main(x: u32) -> u32{ f<foo_t:1>(x) }

2. Get error:

0002:
0003: fn f<N:u32>(x: u32) -> u32 { N + x }
0004: fn main(x: u32) { f<foo_t:1>(x) }
~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~^ ParseError: comparison operators cannot be chained
0005:

3. Change foo_t:1 to bits[32]:1.
4. Compile succeeds.
5. Change foo_t:1 to u32:1.
6. Compile succeeds.

Expected behavior

1. should be equivalent to 3. and 5.
