Use volatile pointers when attempting to trigger SIGSEGVs
Clang fails to compile a number of files with the following warning:
indirection of non-volatile null pointer will be deleted, not trap
[-Wnull-dereference]. This commit qualifies the relevant pointers
with 'volatile'.
gdb/testsuite/ChangeLog:
* gdb.base/bigcore.c (main): Use a volatile pointer when
attempting to trigger a SIGSEGV.
* gdb.base/gcore-relro-pie.c (break_here): Likewise.
* gdb.base/gcore-tls-pie.c (break_here): Likewise.
* gdb.base/savedregs.c (thrower): Likewise.
* gdb.mi/mi-syn-frame.c (bar): Likewise.
