In x86 asm-speak, relative jumps and calls are called
simply "relative" (meaning that instructions contain
an offset relative to current instruction pointer).

I propose to use the "relative" term when you refer
to such branch instructions.
Not, say, "rip-relative" - that term is used in x86-speak
only for instruction-pointer-relative operands.

	MOV  0x123456(%RIP), %RCX

*This* is rip-relative offset.
