Use libm_alias_double for sparc.
Continuing the preparation for additional _FloatN / _FloatNx function aliases, this patch makes sparc libm function implementations use libm_alias_double to define function aliases (with consequent simplification where compat symbol handling is now done by those macros rather than locally in architecture-specific code).

sparc: Assume VIS3 support
This patch assumes VIS3 support by binutils, which is supported since version 2.22. This leads to some code simplification, mostly on multiarch build where there is only one variant instead of previously two (whether binutils supports VIS3 instructions or not).

Remove useless SPARC signbit aliases.
The SPARC implementations of __signbit* functions have aliases signbit, signbitf, signbitl. These are useless, as they aren't exported from the shared libraries (only the __signbit* functions are exported, to be used by the type-generic signbit macro with older compilers). This patch removes the useless aliases. Tested (compilation only) with build-many-glibcs.py for sparc64-linux-gnu and sparcv9-linux-gnu. * sysdeps/sparc/sparc32/fpu/s_signbit.S (signbit): Remove alias.

sparc64: add a VIS3 version of ceil, floor and trunc
sparc64 passes floating point values in the floating point registers. As the the generic ceil, floor and trunc functions use integer instructions, it makes sense to provide a VIS3 version consisting in the the generic version compiled with -mvis3. GCC will then use movdtox, movxtod, movwtos and movstow instructions. sparc32 passes the floating point values in the integer registers, so it doesn't make sense to do the same.

sparc: remove ceil, floor, trunc sparc specific implementations
The ceil, floor and trunc functions on sparc do not fully follow the
standard and trigger an inexact exception when presented a value which
is not an integer. Since glibc 2.24 this causes a few tests to fail,
for instance:
testing double (without inline functions)
Failure: ceil (lit_pi): Exception "Inexact" set
Failure: ceil (-lit_pi): Exception "Inexact" set
Failure: ceil (min_subnorm_value): Exception "Inexact" set
Failure: ceil (min_value): Exception "Inexact" set
Failure: ceil (0.1): Exception "Inexact" set
Failure: ceil (0.25): Exception "Inexact" set
Failure: ceil (0.625): Exception "Inexact" set
Failure: ceil (-min_subnorm_value): Exception "Inexact" set
Failure: ceil (-min_value): Exception "Inexact" set
Failure: ceil (-0.1): Exception "Inexact" set
Failure: ceil (-0.25): Exception "Inexact" set
Failure: ceil (-0.625): Exception "Inexact" set
I tried to fix that by using the same strategy than used on other
architectures, that is by saving the FSR register at the beginning
and restoring it at the end of the function. When doing so I noticed
a comment that this operation might be very costly, so I decided to
do some benchmarks.
The benchmarks below represent the time required to run each of the
function 60 millions of times with different input value. I have done
that in the basic V9 code, the VIS2 code, and using the default C
implementation of the libc, for both sparc32 and sparc64, on a Niagara
T1 based machine and an UltraSparc IIIi. Given I don't have access to a
more recent machine), I haven't been able to test the VIS3 version. Also
it should be noted that it doesn't make sense to do this benchmark for
V8 or earlier as in that case we use the default C implementation. The
results are available in the table below, the "+ fix" version correspond
to the one saving and restoring the FSR.

VIS2 + fix 4.24 5.37 4.30 7.97
C impl 3.63 4.89 3.62 6.38 3.33 4.03
The first thing that should be noted is that the C implementation is
always faster on the Niagara T1 based machine. On the UltraSparc IIIi
the float version on sparc32 is also faster.
Coming back about the fix saving and restoring the FSR, it appears
it has a big impact as expected. In that case the C implementation is
always faster than the fixed implementations.
This patch therefore removes the sparc specific implementations in
favor of the generic ones.

SPARC: fix nearbyint on sNaN input
nearbyint and nearbyintf should not trigger inexact exceptions, but should still trigger an invalid exception for a sNaN input. The SPARC specific implementations of these functions save the FSR at the beginning of the function and restore it at the end to not trigger an inexact exception. This however doesn't work for an sNaN input which need to trigger an invalid exception. Fix that by adding a fcmp instruction using the input value before saving FSR, so that an invalid exception is triggered for a sNaN input. This fixes the math/test-nearbyint-except test on SPARC.
