[Test Plan] Considering the following D program: ``` module t; class uv { int i; } __gshared uv i; int main() { i = new uv(); return 0; // #break } ``` If you build it using `gdc -g -O0 t.d -o t` or `ldc2 -o t.o t.d -g`, run the GDB using the following commands ... ``` b t.d:10 p t.i ``` ... you will notice GDB will complain that "'t.i' has unknown type; cast it to its declared type." [Where problems could occur] * The fix consists of a single line change to the demangler. The worst-case scenario would be breaking the demangling functionality of other programming languages. However, the newer D ABI uses a symbol mangling scheme that is very difficult to confuse with other programming languages. * Incorrect symbol de-mangling may also cause user confusion. However, the patch fixed a fundamental usability issue.
