Polyfill __builtin_assume_aligned for tcc

[cole-miller]

I've been messing around with using Fabrice Bellard's tcc for local builds; this is the only change that's really required for libdqlite to build successfully (have not tried the test suite yet).

The only reason we call __builtin_assume_aligned is to silence a warning from GCC/Clang about unaligned accesses; tcc doesn't have that warning.
