Alice Frosi b18a9650f8 test: update devicefilter tests 
The test cases need to take into account the assembly modifications.
The instruction:
	LdXMemH dst: r2 src: r1 off: 0 imm: 0
has been replaced with:
        LdXMemW dst: r2 src: r1 off: 0 imm: 0
        And32Imm dst: r2 imm: 65535

Load the full 32 bits word and take the lower 16 bits, instead of
reading just 16 bits.

Same fix as 07bae05e61
