Zachary Turner 7655f081e8 Fix many -Wsign-compare and -Wtautological-constant-compare warnings.
Most of the -Wsign-compare warnings are due to the fact that
enums are signed by default in the MS ABI, while the
tautological comparison warnings trigger on x86 builds where
sizeof(size_t) is 4 bytes, so N > numeric_limits<unsigned>::max()
is always false.
