  [MC] Properly report errors for .subsection

For the out-of-range error, MCConstantExpr doesn't have a location, so we
can only show "<unknown>:0:".

Also, allow subsection numbers up to 2147483647, which is the maximum value GNU
assembler supports. (GNU assembler also supports negative numbers.)
