Bug Summary and Steps to Reproduce

Bug Summary:
When aliasing is used for struct that uses same name as namespace then IntelliSense shows error.

Steps to reproduce:

1. Paste in code:

namespace AAA
{
    struct AAA
    {
        int integer;
    };

    int AAAtest(int a)
    {
        return a + 10;
    }
}

namespace BBB
{
using AAA = AAA::AAA; // shows error

void test(AAA *aa)
{
    aa->integer++;
    int result = ::AAA::AAAtest(10);
}
}

2. Error overloaded function "AAA::AAA::AAA" is not a type nameC/C++(757) will be shown on mouse hover over using AAA = AAA::AAA; line.

Expected behavior:
No error should be shown here.
Code compiles using clang version 14.0.6 Android (8490178, based on r450784d) (other compilers not tested).

Hi @mehlian . Thanks for reporting this. Since this also repro's in VS (which shares the same IntelliSense implementation), I opened an issue against VS internally. (ID 2255630)
