Krzysztof Parzyszek 40a605f1be [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.

Krzysztof Parzyszek 152414595b [Hexagon] Crash in instruction selection for insert_vector_elt for HVX
A wrong type was passed to insertVector, causing an out-of-bounds value
to be added an an operand to HexagonISD::INSERT. This later failed in
instruction selection.
