middle-end/98793 - properly handle BLKmode vectors in vector_element_bits
The previous change made AVX512 mask vectors correct but disregarded
the possibility of generic (BLKmode) boolean vectors which are exposed
by the frontends already.

PR middle-end/98793
* tree.c (vector_element_bits): Key single-bit bool vector on
integer mode rather than not vector mode.
* gcc.dg/pr98793.c: New testcase.
