findMaskR8() lacked an isDuplex() check, unlike findMaskR6(),
findMaskR11(), and findMaskR16() which all handle duplex instructions.
When the assembler generates R_HEX_8_X on a duplex SA1_addi instruction
(e.g. `{ r0 = add(r0, ##target); memw(r1+#0) = r2 }`), the wrong mask
0x00001fe0 placed relocation bits at [12:5] instead of [25:20],
corrupting the low sub-instruction (e.g. memw became memb).
Add the isDuplex() check returning 0x03f00000, and add a comprehensive
test covering all duplex instruction x relocation type combinations
across findMaskR6, findMaskR8, findMaskR11, and findMaskR16.
