Francesco Petrogalli f5046224cf [llvm][AArch64] Simplify (and (sign_extend..) #bitmask). ...

Fold

    VT = (and (sign_extend NarrowVT to VT) #bitmask)

into

    VT = (zero_extend NarrowVT)

With this combine, the test replaces a sign extended load + an
unsigned extention with a zero extended load to render one of the
operands of the last multiplication.
