gdb: remove unnecessary NULL checks before xfree
I was inspired by a series of patches merged by Alan Modra in the other projects, so I did the same in GDB with a bit of Coccinelle and grep. This patch removes the unnecessary NULL checks before calls to xfree. They are unnecessary because xfree already does a NULL check. Since free is supposed to handle NULL values correctly, the NULL check in xfree itself is also questionable, but I've left it there for now. gdb/ChangeLog: * coffread.c (patch_type): Remove NULL check before xfree. * corefile.c (set_gnutarget): Likewise. * cp-abi.c (set_cp_abi_as_auto_default): Likewise. * exec.c (build_section_table): Likewise. * remote.c (remote_target::pass_signals): Likewise. * utils.c (n_spaces): Likewise. * cli/cli-script.c (document_command): Likewise. * i386-windows-tdep.c (core_process_module_section): Likewise. * linux-fork.c (struct fork_info) <~fork_info>: Likewise.
