  - Merge macros depending on the flags being preserved between calls
    into a single "__asm"-statement as GCC doesn't guarantee their
    consecutive output even when using consecutive "__asm __volatile"-
    statement for them. Remove the otherwise unnecessary "__volatile". [1]
  - The inline assembler instructions used here alter the condition
    codes so add them to the clobber list accordingly.
  - The inline assembler instructions used here uses output operands
    before all input operands are consumed so add appropriate modifiers.
