[PATCH] Add constant folding for _mm*movemask* intrinsics (PR target/85317)

Hi! The following patch handles constant folding of the builtins used in *movemask* intrinsics - they have single operand and the only useful folding seems to be if the argument is VECTOR_CST, we can do what the instruction would do on that input and return the resulting INTEGER_CST. Bootstrapped
