It would be trivially "optimized" out of the box, even when compiling with
Tiny C or in debug mode.

Such a compiler is already slowed down by memset(3) calls for initializing objects and lack of other optimizations.  I doubt a few more memcpy(3) calls would make that much of a difference.

NB: git as compiled with TCC fails several tests, alas.  Builds wickedly fast, though.

Hmm, a couple of years ago, I used tcc to build git and it worked
just fine (and it passed all tests). Prompted by this note, I just
built tcc from the current mob branch (@5420bb8) and built git OK,
but, yes, lots of tests now fail. :(
