The commit short log (first line of the commit log) should at least say
'snorm_to_float' instead of 'one of the format helper functions'. It could
probably have a more informative summary of what the change does as well.

Should it be if (x <= -MAX_INT(src_bits))? Even if the else case
is guaranteed to produce -1.0f for x == -MAX_INT(src_bits), it seems like
wasted effort.
