    arm: Allow building assembly in thumb mode · 4a9b6e51

    Windows on arm is thumb2 only.
    
    Add the necessary "it" instructions before conditionally executed
    instructions (which doesn't emit any extra instructions when not
    building in thumb mode). The number of "it" instructions could
    be reduced in some places by reordering the instructions, but keeping
    them as they were originally to avoid any impact on existing
    targets.
    
    Remove redundant .arm directives; the assembler normally starts out
    in that mode anyway, and for windows we shouldn't override the
    default mode.
