[64/77] Add a scalar_mode class
This patch adds a scalar_mode class that can hold any scalar mode,
specifically:
- scalar integers
- scalar floating-point values
- scalar fractional modes
- scalar accumulator modes
- pointer bounds modes
To start with this patch uses this type for GET_MODE_INNER.
Later patches add more uses.
