[Hexagon] Don't use garbage mask in HvxSelector::shuffp2
...
The function shuffp2 was breaking up a wide shuffle into a pair of
narrower ones, except that the narrower shuffle masks were actually
uninitialized.

[Hexagon] Only process bitcasts of vsplats when selecting const vectors
...
Selecting of constant HVX vectors involves some "manual processing",
which mishandled an unrelated BITCAST operation causing a selection
error.

[Hexagon] Implement basic vector operations on vectors vNi1
...
In addition to that, make sure that there are no boolean vector types that
are associated with multiple register classes. Specifically, remove v32i1
and v64i1 from integer register classes. These types will correspond to
results of vector comparisons, and as such should belong to the vector
predicate class. Having them in scalar registers as well makes legalization
ambiguous.

[Hexagon] Fix wrong order of operands for vmux
...
Shuffle generation uses vmux to collapse vectors resulting from two
individual shuffles into one. The indexes of the elements selected
from the first operand were indicated by 0xFF in the constant vector
used in the compare instruction, but the compare (veqb) set the bits
corresponding to the 0x00 elements, thus inverting the selection.
Reverse the order of operands to vmux to get the correct output.
