gcc-gdb-test.exp: Handle old GDB "short int" and "long int" types.

Old GDB might show short and long as short int and long int. This made
gcc.dg/guality/const-volatile.c ans restrict.c fail on older GDBs.
According to the patch that changed this in newer versions of GDB
this was a bug: https://sourceware.org/ml/gdb-patches/2012-09/msg00455.html

The patch transforms the types "short int" and "long int" coming from
GDB to plain "short" and "long". And a variant has been added to the
const-volatile.c testcase to make sure short and long long are handled
correctly now with older GDB.

gcc/testsuite/ChangeLog

	* lib/gcc-gdb-test.exp (gdb-test): Transform gdb types "short int"
	and "long int" to plain "short" and "long".
	* gcc.dg/guality/const-volatile.c (struct bar): New struct
	containing short and long long fields.
	(bar): New variable to test the type.
