Do not build soft-fp code at all for powerpc64-linux-gnu.

When I added support for using soft-fp in libgcc
<https://gcc.gnu.org/ml/gcc-patches/2006-03/msg00689.html>, libgcc
configuration was still done in the gcc/ directory, meaning that the
variables set in makefile fragments could not depend on the multilib
being built.  Thus, building the soft-fp code for powerpc64-linux-gnu
was disabled in the same way as had been done with fp-bit: the code
was built, but with #ifndef __powerpc64__ wrappers around it so that
the resulting objects were empty.

Now that libgcc configuration is done in the toplevel libgcc
directory, such uses of softfp_wrap_start / softfp_wrap_end are better
replaced by configure-time conditionals that determine whether to use
soft-fp for a given multilib.  This patch does so for
powerpc*-*-linux*.  The same would appear to apply to
powerpc*-*-freebsd* (using rs6000/t-freebsd64), but I have not made
any changes there.  t-ppc64-fp is also used by AIX targets, but they
don't use soft-fp anyway so the changes are of no consequence to them.

The same principle of replacing softfp_wrap_start / softfp_wrap_end
with configure-time conditionals also applies to
softfp_exclude_libgcc2, which was intended for cases where soft-fp is
being used on hard-float multilibs and so it is desirable on those
multilibs for a few functions to come from libgcc2.c rather than
soft-fp (but the soft-fp versions would be more efficient on
soft-float multilibs).  Now we have hardfp.c and t-hardfp, those are
better to use in that case, to minimize the size of the bulk of the
functions that are only present for ABI compatibility and should never
be called by newly compiled code.

I intend followup patches to switch 32-bit hard-float multilibs to use
t-hardfp as far as possible (for all non-libgcc2.c operations for
classic hard float; for all except __unord* for e500v2; for all SFmode
operations except __unordsf2 for e500v1).  After that will come making
the soft-fp operations, in the remaining cases for which they are
built because they are actually needed for code compiled by current
GCC, into compat symbols when building for glibc 2.19 or later, so
that the glibc versions (with exception and rounding mode support) get
used instead (2.19 or later is needed for all the functions to be
exported from glibc as non-compat symbols).  In turn, that is required
before implementing TARGET_ATOMIC_ASSIGN_EXPAND_FENV for soft-float
and e500, as that can only be properly effective when GCC-compiled
code is actually interoperating correctly with the exception and
rounding mode state used by <fenv.h> functions.

Tested with no regressions with cross to powerpc64-linux-gnu (in
addition, verified that stripped libgcc_s.so.1 is identical before and
after the patch).

* config.host (powerpc*-*-linux*): Only use soft-fp for 32-bit
configurations.
* config/rs6000/t-ppc64-fp (softfp_wrap_start, softfp_wrap_end):
Remove variables.

compiler, runtime: Add type information to single object allocation.

From-SVN: r216490

reflect: allocate correct type in assignTo and cvtT2I

Backport https://codereview.appspot.com/155450044 from the
master Go library.  Original description:

I came across this while debugging a GC problem in gccgo.
There is code in assignTo and cvtT2I that handles assignment
to all interface values.  It allocates an empty interface even
if the real type is a non-empty interface.  The fields are
then set for a non-empty interface, but the memory is recorded
as holding an empty interface.  This means that the GC has
incorrect information.

This is extremely unlikely to fail, because the code in the GC
that handles empty interfaces looks like this:

obj = nil;
typ = eface->type;
if(typ != nil) {
        if(!(typ->kind&KindDirectIface) || !(typ->kind&KindNoPointers))
                obj = eface->data;

In the current runtime the condition is always true--if
KindDirectIface is set, then KindNoPointers is clear--and we
always want to set obj = eface->data.  So the question is what
happens when we incorrectly store a non-empty interface value
in memory marked as an empty interface.  In that case
eface->type will not be a *rtype as we expect, but will
instead be a pointer to an Itab.  We are going to use this
pointer to look at a *rtype kind field.  The *rtype struct
starts out like this:

type rtype struct {
        size          uintptr
        hash          uint32            // hash of type; avoids computation in hash tables
        _             uint8             // unused/padding
        align         uint8             // alignment of variable with this type
        fieldAlign    uint8             // alignment of struct field with this type
        kind          uint8             // enumeration for C

An Itab always has at least two pointers, so on a
little-endian 64-bit system the kind field will be the high
byte of the second pointer.  This will normally be zero, so
the test of typ->kind will succeed, which is what we want.

On a 32-bit system it might be possible to construct a failing
case by somehow getting the Itab for an interface with one
method to be immediately followed by a word that is all ones.
The effect would be that the test would sometimes fail and the
GC would not mark obj, leading to an invalid dangling
pointer.  I have not tried to construct this test.

I noticed this in gccgo, where this error is much more likely
to cause trouble for a rather random reason: gccgo uses a
different layout of rtype, and in gccgo the kind field happens
to be the low byte of a pointer, not the high byte.
