Load FP environment before FP operation
Since floating-point operation may trigger floating-point exceptions,
we need to load the current floating-point environment before any
floating-point operations.
[BZ #19465]
* sysdeps/ieee754/dbl-64/s_fma.c (__fma): Load the current
floating-point environment before any floating-point operation
which may trigger floating-point exceptions.

Use TIME_T_MAX and TIME_T_MIN in tst-mktime2.c
GCC 5.3 compiles
for (time_t_max = 1; 0 < time_t_max; time_t_max *= 2)
continue;
into an infinite loop with -Os. We can copy TIME_T_MAX and TIME_T_MIN
from time/mktime.c.
[BZ #19466]
* time/tst-mktime2.c (TYPE_SIGNED): New.
(TYPE_MINIMUM): Likewise.
(TYPE_MAXIMUM): Likewise.
(TIME_T_MIN): Likewise.
(TIME_T_MAX): Likewise.
(do_test): Initialize time_t_max and time_t_min with TIME_T_MAX
and TIME_T_MIN.

Add string_private.h to define _STRING_ARCH_unaligned
_STRING_ARCH_unaligned is used unconditionally in glibc. But
<bits/string.h>, which defines _STRING_ARCH_unaligned, isn't
included with -Os. Since _STRING_ARCH_unaligned is internal to
glibc and may change between glibc releases, it should be made
private to glibc. This patch adds string_private.h to define
_STRING_ARCH_unaligned, which is included unconditionally from
internal <string.h> for glibc build.
[BZ #19462]
* bits/string.h (_STRING_ARCH_unaligned): Removed.
* include/string.h: Include <string_private.h>.
* sysdeps/aarch64/bits/string.h: Renamed to ...
* sysdeps/aarch64/string_private.h: This.
* sysdeps/generic/string_private.h: New file.
* sysdeps/s390/string_private.h: Likewise.
* sysdeps/x86/string_private.h: Likewise.
* sysdeps/m68k/m680x0/m68020/bits/string.h: Renamed to ...
* sysdeps/m68k/m680x0/m68020/string_private.h: This.
* sysdeps/s390/bits/string.h (_STRING_ARCH_unaligned): Removed.
* sysdeps/sparc/bits/string.h (_STRING_ARCH_unaligned): Likewise.
* sysdeps/x86/bits/string.h (_STRING_ARCH_unaligned): Likewise.
