Previously had wonky line pointer in asm_main. New interface simpler and more portable. Add tests for ASSERT_EQ_ and family in arm and aarch64, previously on x86_64. ASSERT_EQ_ and family in ARM can now either take =123, =addr or var, before this the = was added on macros so var was not possible. Define the main function directly in assembly, the C driver was useless.
