As GDCFLAGS is overriden by the top-level make file with '-O2 -g',
libphobos ends up always being built with all contracts, invariants, and
asserts compiled in. This adds a new configurable that defaults to omit
compiling any run-time checks into the library using '-frelease'.
Other choices either set the flags '-fno-release', enabling all run-time
checks, or '-fassert', which only compiles in asserts.
The omission of compiling in contracts results in a smaller library
size, with faster build times.

This option is not useful on its own as all posix modules require the
compiler to predefine version(Posix) anyway. So the option has been
removed, and logic moved into DRUNTIME_OS_SOURCES, where the conditional
DRUNTIME_OS_POSIX is set instead.

* configure.ac: Remove DRUNTIME_OS_UNIX.

DRUNTIME_OS_POSIX is true.

* m4/druntime/os.m4 (DRUNTIME_OS_UNIX): Remove, move AM_CONDITIONAL
logic to...
(DRUNTIME_OS_SOURCES): ...here. Rename conditional to
DRUNTIME_OS_POSIX.
This moves WARN_DFLAGS from GDCFLAGS to AM_DFLAGS so it is always
included in the build and testsuite of libphobos. Currently, this
doesn't happen as GDCFLAGS is overriden by it being set at the
top-level.
libphobos/ChangeLog:
* Makefile.in: Regenerate.

Improves the versioning of IeeeFlags and FloatingPointControl code and
unit-tests, making it clearer which targets can and cannot support it.

With this patch we get rid of the usage of the glibc-internal symbol
__tls_get_addr_internal.
If build with multilib, the file
gcc/libphobos/libdruntime/config/systemz/get_tls_offset.S is used
for both configurations: systemz and s390.
Therefore both implementations are now in the systemz file which
uses an "#ifdef __s390x__" in order to distinguish both cases.
The s390 file is just including the systemz one.

* m4/druntime/cpu.m4: Add s390x and s390.
The ordering of some fields in struct sigaction on s390x (64bit)
differs compared to s390 and other architectures.
This patch adjusts this order according to the definition of
<glibc-src>/sysdeps/unix/sysv/linux/s390/bits/sigaction.h
Without this fix e.g. the call
sigaction( suspendSignalNumber, &sigusr1, null ) in thread.d
leads to setting the sa_restorer field to 0xffffffffffffffff.
In case a signal, the signal handler returns to this address
and the process stops with a SIGILL.
This was observable in several execution testcases on s390x:

libphobos.druntime_shared/core/thread.d

These modules depend on a mixture between how the compiler emits
run-time module information, and what functions are exposed by the
platform to inquire about loaded global and thread-local data sections.
As the upstream implementation is written to work only with how the
reference D compiler writes out data, much of what is present does not
apply to the GCC D front-end. So it has been moved to a non-upstream
location in the source tree, where most of it will be rewritten once
each port has been completed.
The only tested module sections/elf_shared.d has been cleaned up so that
all deprecated declarations have been removed, as well as the brittle
module collision checking, which required bss_sections.c. All other
ports have been left unchanged apart from a commonizing of attributes.
