OPTIM: halog: improve field parser speed for modern compilers

Modern compilers were producing producing less efficient code in the
field_start() loop, by not emitting two conditional jumps for a single
test. However by reordering the test we can merge the optimal case and
the default one and get back to good performance so let's simplify the
test. This improves the parsing speed by 5%.
