  [ms] [llvm-ml] Add support for ALIGN, EVEN, and ORG directives

Match ML.EXE's behavior for ALIGN, EVEN, and ORG directives both at file level and in STRUCTs.

We currently reject negative offsets passed to ORG inside STRUCTs (in ML.EXE and ML64.EXE, they wrap around as for an unsigned 32-bit integer).

Also, if a STRUCT is declared using an ORG directive, no value of that type can be defined.
