Debugger symbol table fix

Browse Source 
const structs are wrapped in definedType.  The debugger symbol table code is unaware of this, which results in missing or incomplete entries.

example:

const struct { int a; int b; } cs;

cs:  isForwardDeclared =    false; class = ident
    4 byte constant defined type of
    4 byte struct: 223978

const struct { int a; int b; } *pcs;

pcs:  isForwardDeclared =    false; class = ident
    4 byte  pointer to
    4 byte constant defined type of
    4 byte struct: 224145

const struct { const struct { const int a; } a[2]; } csa[5];

csa:  isForwardDeclared =    false; class = ident
    20 byte 5 element array of
    4 byte constant defined type of
    4 byte struct: 225155

const struct { const struct { const int a; } a[2]; } *cspa[5];

cspa:  isForwardDeclared =    false; class = ident
    20 byte 5 element array of
    4 byte  pointer to
    4 byte constant defined type of
    4 byte struct: 224850

This change unwraps the definedType so the underlying type info can be placed in the debugger symbol table.
