Tom de Vries 94cb375411 [gdb/testsuite] Compile infcall-nested-structs.exp with -O2
As mentioned in commit 745ff14e6e "[gdb/tdep] Fix 'Unexpected register class'
assert in amd64_push_arguments", of the 12 KFAILs added there, 3 are KPASSing
with g++ 4.8.5.

The KPASSes are due to:
- gdb incorrectly expecting the second half of the result of function
  rtn_str_struct_02_01 in register %rdx.
- rtn_str_struct_02_01 using %rdx as a temporary, thereby accidentally setting
  it to the expected value.

Reduce the chance of hiding errors due accidental register settings by
compiling the test-case with -O2.

This fixes the KPASSes when applied on top of commit 745ff14e6e.

Tested on x86_64-linux.

Tested with g++ 4.8.5, 7.4.1, 8.3.1, 9.2.1.

gdb/testsuite/ChangeLog:

2019-10-21  Tom de Vries  <tdevries@suse.de>

	* gdb.base/infcall-nested-structs.c: Add
	__attribute__((noinline,noclone)) to all functions.
	(call_all): Add missing variable initialization.  Simplify return value.
	(breakpt): Increment volatile variable, to prevent call from being
	optimized out.
	* gdb.base/infcall-nested-structs.exp: Compile with -O2.

		   README for GNU development tools

This directory contains various GNU compilers, assemblers, linkers, 
debuggers, etc., plus their support routines, definitions, and documentation.

If you are receiving this as part of a GDB release, see the file gdb/README.
If with a binutils release, see binutils/README;  if with a libg++ release,
see libg++/README, etc.  That'll give you info about this
package -- supported targets, how to use it, how to report bugs, etc.

It is now possible to automatically configure and build a variety of
tools with one command.  To build all of the tools contained herein,
run the ``configure'' script here, e.g.:

	./configure 
	make

To install them (by default in /usr/local/bin, /usr/local/lib, etc),
then do:
	make install

(If the configure script can't determine your type of computer, give it
the name as an argument, for instance ``./configure sun4''.  You can
use the script ``config.sub'' to test whether a name is recognized; if
it is, config.sub translates it to a triplet specifying CPU, vendor,
and OS.)

If you have more than one compiler on your system, it is often best to
explicitly set CC in the environment before running configure, and to
also set CC when running make.  For example (assuming sh/bash/ksh):

	CC=gcc ./configure
	make

A similar example using csh:

	setenv CC gcc
	./configure
	make

Much of the code and documentation enclosed is copyright by
the Free Software Foundation, Inc.  See the file COPYING or
COPYING.LIB in the various directories, for a description of the
GNU General Public License terms under which you can copy the files.

REPORTING BUGS: Again, see gdb/README, binutils/README, etc., for info
on where and how to report problems.
