Heng Li f22a94e868 r538: fixed a long existing bug in HPC k-mer (#47) ...

This bug may lead to a wrong minimizer when a HPC k-mer is longer than 256bp.
When there is a seed match involving this wrong HPC k-mer, the correct seed
sequences do not match in fact. This violates the assumption in align.c and
subsequently causes a segfault, which is what #47 has caught. This bug lurked
in the earliest piece of code and affected all released minimap2 versions so
far. It is extremely rare and does not affect the prebuilt GRCh37/38 indices.
