Partial patch for 682.pdf.SIGFPE.f3.1033

This patch fixes a non-fatal bad access in the test to show the "Weird tile
index in JPX stream" warning by moving a test of an index before using the
index.

With libopenjpeg, it fails with a divide by 0 in j2k_decode.

Without libopenjpeg, it gets stuck trying to parse a 622236252 x 19 bitmap in
JBIG2Stream::readGenericBitmap() called by JBIG2Stream::readSymbolDictSeg().
Is there a way to detect an unrealistically large bitmap?
