[PATCH] Set print symbol off in some tests

- Subject: [PATCH] Set print symbol off in some tests
- Authentication-results: sourceware.org; auth=none
GDB in default prints the symbol associated on an address, and tests
assume that there is no symbol on address zero. However, on bare
metal target, address may be mapped to zero and there may be a
symbol. Then, some tests fails as below:
print const_cast<void *> (0)^M
$8 = (void *) 0x0 <_ftext>^M
(gdb) FAIL: gdb.cp/casts.exp: const_cast of 0
p acp->c1^M
$9 = (A *) 0x0 <_ftext>^M
(gdb) FAIL: gdb.cp/class2.exp: p acp->c1
This patch is to set print symbol off in these tests, like what
I did previously https://sourceware.org/ml/gdb-patches/2014-07/msg00257.html

* gdb.cp/casts.exp: Set print symbol off.
* gdb.cp/class2.exp: Likewise.
* gdb.cp/overload.exp: Likewise.
* gdb.cp/templates.exp: Likewise.
