PR30793, kvx_reassemble_bundle index 8 out of bounds
While the patch already committed for pr30793 prevents the asan error,
there is a problem: Now the last element of bundle_words never gets
written. That's very likely wrong, or KVXMAXBUNDLEWORDS is too big.
So this patch rearranges things a little to support writing of all of
bundle_words and does the parallel bit checking only when filling
bundle_words. In the normal case, kvx_reassemble_bundle will see
bundle_words[word_count-1] with the parallel bit clear and all other
words having it set. In the error case where all words in
bundle_words have the parallel bit set, kvx_reassemble_bundle will be
passed a wordcount of KVXMAXBUNDLEWORDS + 1. I've also made
kvx_reassemble_bundle return true for success rather than zero, and
removed the unnecessary check for zero wordcount.
PR 30793
* kvx-dis.c (kvx_reassemble_bundle): Return bool, true on success.
Fail if wordcount is too large. Don't check for wordcount zero.
Don't check kvx_has_parallel_bit.
(print_insn_kvx): Rewrite code reading bundle_words as a for loop.
Don't stop reading at KVXMAXBUNDLEWORDS - 1.
(decode_prologue_epilogue_bundle): Similarly.
