commonlib: Add assembly optimization for ipchksum() on x86
This patch adds a bit of optimized assembly code to the ipchksum()
algorithm for x86 targets in order to take advantage of larger load
sizes and the add-with-carry instruction. The same assembly (with one
minor manual tweak) works for both 32 and 64 bit mode (with most of the
work being done by GCC which automatically inserts `rax` or `eax` in the
inline assembly depending on the build target).
