Refactor constants referring to sizes (remove suffix)

Keeping the prefix in the constant in the constant value makes arithmetic ugly (since the prefix needs to be stripped).

For consistency, all the constants using this format have had the same treatment applied. There's an argument for leaving their format inconsistent, but I prefer not to.
