x86/Linux: reenable all-stop on top of non-stop

Since the record-btrace target now supports non-stop mode, we no
longer need to force-disable as-ns on x86.

2015-09-30 Pedro Alves <palves@redhat.com>

* linux-nat.c (linux_nat_always_non_stop_p): Always return 1.
* x86-linux-nat.c (x86_linux_always_non_stop_p): Delete.
(x86_linux_create_target): Don't install
x86_linux_always_non_stop_p.

gdbarch.h: Change gdbarch_info::tdep_info's type to void *

As reported by Ulrich here:

https://sourceware.org/ml/gdb-patches/2015-09/msg00604.html

The system compiler (gcc 4.1) in Centos 5 doesn't like that we cast to a
pointer to a type that doesn't exist. I see no real value in using this
kind iof construct over just using void *. So this patch changes the
tdep_info field to void * and removes the casts. Even in C++, we
should not need an explicit cast when assigning to a void *.

py-type.exp: Do not run tests if binary fails to build

I noticed this while working on the test case. I believe it would make
sense to skip running the tests if the binary failed to build. Although
I would understand the opposite argument: if the binary does not build
for some reason, we probably want to know about it, and some catastrophic
failures in the tests might alarm us better than a timid "UNTESTED".

infcmd.c: Don't attempt to record a NULL value after a finish command.

Architectures which use RETURN_VALUE_STRUCT_CONVENTION will have a
NULL return value after executing a finish command. See get_return_value()
in infcmd.c.

This patch avoids an eventual SIGSEV (caused by attempting to
derefrence a NULL pointer) by adding a suitable test to
finish_command_fsm_should_stop().

I encountered this problem while testing msp430:

msp430: Fix bug regarding large memory model inferior function call arguments.

This change causes reference, struct, and union arguments to be treated
the same as pointer arguments when determining the size of the value to
place into a register.

The case for doing this for reference arguments is obvious.

The msp430 ABI specifies that struct and union arguments are passed by
reference. This is why they're treated in the same manner as pointer
and reference arguments when computing the size of the value to place
into a register.

In my testing using this multilib...

Adjust the output section size to skip gap fills

In objcopy, copy_object calls copy_section to copy contents of input
section to output section. When --gap-fill= is used, objcopy extends
the size of output sectios to fill gaps between output sections with
gap fills. In this case, we adjust the output section size to skip
gap files to avoid reading beypond the input section buffer before
calling copy_section and restore the output section size after input
sections have been copied.
