Mea culpa. Upon further thinking, two things strike me:
1) As suggested, there's no way to instruct the front-end to
align functions to byte boundaries outside of "optimise for
speed" command line flags
2) I would have heavily relied on incremental linking to iterate
on these tests when trying to work out how the processor behaved.
I expect MSVC's incremental linker would turn out to be just
rubbish enough to not care about how those flags originally
behaved.

It would be nice to get this technique put into std.algorithm!
The code I wrote originally was C++ code with intrinsics. But I
can certainly look at adapting it to DMD/LDC. The DMD frontend
providing natural mappings for Intel's published intrinsics would
be massively beneficial here.
