[Bug] Fix array functions arguments mismatch (#10549)
Currently, we convert array<Int> to array<BigInt>
For example, the input array_sum([1, 2, 3]) can match function
array_sum(Array<Int>) as well as array_sum(Array<BigInt>).
But when a function has more than one argument, the function may be match
incorrectly.
For example, the input array_contains([1, 2, 3], 2147483648) will match the
function array_contains(Array<BigInt>, BigInt), but the correct match should be
array_contains(Array<Int>, Int)
The correct match should be:
array_contains([1, 2, 3], 1) match array_contains(Array<Int>, Int)
array_contains([1, 2, 3], 2147483648) match array_contains(Array<Int>, Int)
array_contains([2147483648, 2147483649, 2147483650], 2147483648) match
array_contains(Array<BigInt>, BigInt)
now is:
array_contains([1, 2, 3], 1) match array_contains(Array<Int>, Int)
array_contains([1, 2, 3], 2147483648) match array_contains(Array<BigInt>,
BigInt)
array_contains([2147483648, 2147483649, 2147483650], 2147483648) match
array_contains(Array<BigInt>, BigInt)
And this will cause some trouble.
Assume that there are two functions being defined:
Int array_functions(Array<Int>, Int)
BigInt array_functions(Array<BigInt>, BigInt)
And array_functions([1,2,3], 2147483648) will match BigInt
array_functions(Array<BigInt>, BigInt), but the result type should not be
BigInt, but should be Int.
