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". Differential Revision: https://reviews.llvm.org/D49821 llvm-svn: 338063

// Test that we produce image-relative relocations (IMAGE_REL_I386_DIR32NB
