[Bug c++/20123] New: mangled name of typeid doesn't encode cv-qualifer.

[yanliu at ca dot ibm dot com]

Here is a testcase:
#include <typeinfo>
int const volatile v5[10] = {0};
int
main (int argc, char **argv) {
  const std::type_info& t = typeid (::v5);
}

According to Itanium C++ ABI, the mangled name of typeid(::v5) should follow 
the following grammer rules:
 <mangled-name> ::= _Z <encoding>
    <encoding> 	::= <special-name>
       <special-name> ::= TI <type>	# typeinfo structure
          <type> ::= <array-type>
             <array-type> ::= A <positive dimension number> _ <element type>

To my understanding, the element type follows the <type> rule and is used to 
encode the type of variable v5[10]:
                <type> ::= <CV-qualifiers> <type>
                   <CV-qualifiers> ::= [r] [V] [K] # restrict (C99), volatile, 
const


So the mangled name should be: __ZTIA10_VKi. But using gcc 4.0 compiler, I am 
getting "__ZTIA10_i" mangled name instead. 

Please verify the problem, thanks.
