libgo: update to final Go 1.8 release

    Along with the update this fixes a problem that was always present but
    only showed up with the new reflect test.  When a program used a
    **unsafe.Pointer and stored the value in an interface type, the
    generated type descriptor pointed to the GC data for *unsafe.Pointer.
    It did that by name, but we were not generating a variable with the
    right name.

rs6000: Fix extendsfdf2 for signaling NaNs

A cast from float to double should turn a signaling NaN into a quiet
NaN, if using -fsignaling-nans.  On PowerPC single-precision floats are
stored as double precision in registers, and so, the cast normally does
nothing.  This causes gcc.dg/pr59833.c to fail (it does such a cast,
and expects a quiet NaN as output).

This patch adds a new pattern, used with -fsignaling-nans in effect,
that creates an frsp instruction (or xsrsp) in this case.  Since the
input already is SFmode, that instruction turns signaling NaNs into
quiet NaNs and does nothing more.

* config/rs6000/rs6000.md (extendsfdf2): Remove default arguments.
If HONOR_SNANS (SFmode) force the input to a register.
(*extendsfdf2_fpr): Add !HONOR_SNANS (SFmode) condition.
(*extendsfdf2_snan): New pattern, used when using SNaNs; it generates
an frsp or similar insn.

testsuite: pr59833.c and pr61441.c should use -fsignaling-nans

The testcases pr59833.c and pr61441.c check whether signaling NaNs as
input to some operation result in quiet NaNs.  Without -fsignaling-nans
this is not guaranteed to happen.  So, this patch add this option to
these testcases.

* gcc.dg/pr59833.c: Add -fsignaling-nans to options.
* gcc.dg/pr61441.c: Ditto.
