2906 and neutralize STO_SH5_ISA32 found on the symbol definition.

2908 There is a problem, though: We want to fill in the hash-table entry for
2909 this symbol and signal to the caller that no further processing is
2910 needed. But we don't have the index for this hash-table entry. We
2911 rely here on that the current entry is the first hash-entry with NULL,
2912 which seems brittle. Also, iterating over the hash-table to find that
2913 entry is a linear operation on the number of symbols in this input
2914 file, and this function should take constant time, so that's not good
2915 too. Only comfort is that DataLabel references should only be found in
2916 hand-written assembly code and thus be rare. FIXME: Talk maintainers
