[ARC] Fix conditional move contstraint

Move pattern (movsi_insn) allows predicated instructions to be
instructions which can hold all registers.  However, the conditional
variant doesn't.  This patch fixes this problem.

rs6000, testsuite: Correct the broken_cplxf_arg test

check_effective_target_broken_cplxf_arg is buggy.  It actually tests
if passing complex float works, not if it fails.  Also, it only runs
the test for target powerpc64-linux, but we are biarch, so it should
be powerpc*-linux.

This also changes the early-out conditions to be separate, because
the big combined condition was hard to follow.

This fixes the libstdc++ tests:

Running target unix/-m64
XPASS: 26_numerics/complex/13450.cc execution test
XPASS: 26_numerics/complex/pow.cc execution test

rs6000: float128 on BE and 32-bit

This fixes float128 on BE and on 32-bit.

The configure tests need to use -mabi=altivec for 32-bit, since it is
not the default there.  That also enables the "vector" keyword, used by
the tests.  To do this it temporarily adds a few flags to the CFLAGS
variable.

It also fixes a syntax error in the libgcc_cv_powerpc_float128_hw test
(the function name was missing in the function declaration).

Regenerating config.in (via autoreconf) removed the duplicate definition
of HAVE_SOLARIS_CRTS.

Finally, this adds a "-mfloat128-hardware requires -m64" test to
rs6000.c: all the current patterns need 64-bit registers.  Maybe we'll
want to add float128 hardware support to 32-bit some day, but certainly
not today.

[libstdc++-v3] Fix detection of obsolete isnan

libstdc++-v3 configure checks whether old glibc inline definitions
of isnan would conflict with the libstdc++-v3 definitions and
works around them if so.  But if g++ 6.x build A is used to build
another g++ 6.x B, the configure step for B will pick up the math.h
installed alongside A instead of the glibc version.  configure will
then assume that the workaround isn't necessary, leaving B with a
broken cmath.

isinf already worked around this.  This patch extends the same fix
to isnan.  (Thanks to George for the fix.)
