33d7e138ca sparc: Remove optimized math routines which cause testsuite failures. 
famx{,f}/fmin{,f} and 32-bit lrint cause math testsuite failures
either because they generate incorrect results or they fail to signal
the proper exceptions.

f67d78192c Move wrappers to libm-compat-calls-auto 
This commit moves one step towards the deprecation of wrappers that
use _LIB_VERSION / matherr / __kernel_standard functionality, by
adding the suffix '_compat' to their filenames and adjusting Makefiles
and #includes accordingly.

New template wrappers that do not use such functionality will be added
by future patches and will be first used by the float128 wrappers.

bf79a337ec sparc32/sparcv9: add a VIS3 version of fdim 
sparc32 passes floating point values in the integer registers. VIS3
instructions gives access to the movwtos instruction to directly
transfer a value from an integer register to a floating point register.
Therefore it makes sense to provide a VIS3 version consisting in the
generic version compiled with -mvis3.

8a9f4eb958 sparc: remove fdim sparc specific implementations 
The fdim and fdimf functions on sparc do not fully follow the standard
and do not set errno to ERANGE when the result overflows. Since glibc
2.24 this causes the two following tests to fail:

  Failure: fdim (max_value, -max_value): errno set to 0, expected 34 (ERANGE)
  Failure: fdim_upward (max_value, -max_value): errno set to 0, expected 34 (ERANGE)

It happens that using GCC with the generic C code generates very similar
code to the sparc specific implementations. Therefore this patches
remove them. Note it might still worth adding a vis3 specific version of
fdim on sparc32/sparcv9, this is done in a following patch to ease
backporting.

33ae5b17cd 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.

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.
