14/// AsmCond - Class to support conditional assembly
15///
16/// The conditional assembly feature (.if, .else, .elseif and .endif) is
17/// implemented with AsmCond that tells us what we are in the middle of
18/// processing.  Ignore can be either true or false.  When true we are ignoring
19/// the block of code in the middle of a conditional.
