Shortcomings of ALIGN macros:
- ALIGN_MASK down aligns when there is an wrapping/overflow instead of
throwing an error. This can affect the size assumptions.
- Alignment a's check will be bypassed when ALIGN_MASK is directly
used.
Fix these issues by 1) adding compile time error for non-unsigned type
arguments 2) using unsigned type safe ops for addition and subtraction.
Also, change users of ALIGN to pass unsigned types only.
