compiler: new "binary literal area" at the end of a word's machine code stores constant floats and SIMD vectors; this allows ##load-reference/##load-memory fusion to be performed on x86-64, with a RIP-relative address reaching the data; also simplifies VM since custom relocation types used by the previous 32-bit-only optimization are no longer needed
