[HLSL] Allow array to be initialized from an array of the same type

[llvm-beanz]

HLSL allows a constant-sized array variable to be initialized from an array of the same type.

typedef int4 int8[2];

export void fn(int8 A) {
    int8 a = A;
}

CE

AC: the code above should compile and initialize the local array a by copying A.
