C++ links: x86 Assembly

See also: Computer Architecture -- recommended background (which makes the following significantly more approachable) includes an undergraduate-level course.

Note: The main focus is on the 64-bit variant (x86-64) -- thus, primarily up-to-date materials (i.e., 64-bit, AVX) are preferred.
