[Bug]: Variety of incorrect diagnostic messages generated for duplicate keys in mapping constructors

[pubudu91]

Description

Consider the following:

map<[decimal, int]> m = {
    "1": [1.2, 3],
    "1": [5.6, 7]
};

We get the following error message for the above:

invalid usage of map literal: duplicate key '1'

But when the mapping constructor is used in other expression contexts, it keeps giving different different diagnostic messages of the same variant of the above. e.g.,

bar({
    "1": [1.2, 3],
    "1": [5.6, 7]
});

error: invalid usage of null literal: duplicate key '1'

if {
    "1": [1.2, 3],
    "1": [5.6, 7]
} is map<[decimal, int]> {
    io:println("map");
}

error: invalid usage of boolean literal: duplicate key '1'

var v = {
    "1": [1.2, 3],
    "1": [5.6, 7]
}.toString();

error: invalid usage of string literal: duplicate key '1'
