Ben Clayton 0ce9ab042e tint: Change all ProgramBuilder literals to 'i' or 'u' suffix 
Unsuffixed integer literals are currently treated as i32,
but will shortly become AbstractInteger. To keep tests behaving
identically to how they are currently, change all test literals
to using either 'i' or 'u' suffixes.
