dfc2838892
This updates all assembly source files under ArmVirtPkg to mark exported functions as ASM_FUNC(), which puts them in a separate section, allowing the linker to prune code that is left unused. At the same time, clean up the code to get rid of LoadConstantToReg() instances involving symbol references, each of which emits an absolute literal, and hence and entry in the PE/COFF .reloc table.
