[MC] Add support for the .rva assembler directive for COFF targets
Even though gas doesn't document it, it has been supported there for
a very long time.
This produces the 32 bit relative virtual address (aka image relative
address) for a given symbol. ".rva foo" is essentially equal to
".long foo@imgrel".
