primitive types

There are various builtin primitives in KDLScript, such as:

• integers - fixed width integers
  • i8, i16, i32, i64, i128, i256
  • u8, u16, u32, u64, u128, u256
• floats - fixed with floating point numbers
  • f16, f32, f64, f128
• bool- your old pal the boolean
• ptr - an opaque pointer (void*), used when you're interested in the address as a value (unlike &T)

The lowering of these to Rust is pretty direct, since we're reusing Rust's naming scheme.

The lowering of these to C uses uint8_t and friends for the integers, and then the usual types for the rest.

In the future there will probably be language-specific primitives like c_long...?
