2872 and neutralize STO_SH5_ISA32 found on the symbol definition.

2875 this symbol and signal to the caller that no further processing is
2876 needed. But we don't have the index for this hash-table entry. We
2877 rely here on that the current entry is the first hash-entry with NULL,
2878 which seems brittle. Also, iterating over the hash-table to find that
2879 entry is a linear operation on the number of symbols in this input
2880 file, and this function should take constant time, so that's not good
2881 too. Only comfort is that DataLabel references should only be found in
2882 hand-written assembly code and thus be rare. FIXME: Talk maintainers
