Upgrade mes to 0.26

[Googulator]

This can successfully build a working tcc-mes, but then fails creating unified-libc.c for subsequent tcc bootstrapping.

Fixes #306

[stikonas]

Perhaps we should wait with this until upstream mes figures out what causes so much slowdown.

[Googulator]

If I had to guess, it's probably intentional, due to mescc now running 2 consecutive phases, presumably for optimization.

If I had to guess, it's probably intentional, due to mescc now running 2 consecutive phases, presumably for optimization.

Almost surely it doesn't and duplicate warnings might be just coincidence. Also slow down is not twice, is closer to 10 times. I think I would be more convinced by argument that we need to load more scheme modules now (that were not present in 0.25).

[Googulator]

Is that 10x slowdown on riscv64? On x86, I'm seeing pretty much an exact 2x multiplier.

BTW, the timing of the warnings is also consistent with mescc doing everything twice.
