GCC revision 259524 implemented range check for the vec_splat_{su}{8,16,32}
builtins. However, as a consequence of the implementation, the range check
is not done correctly for the expected vspltis[bhw] instructions. The result
is that we may not get a valid error message if the valid range of the data
is exceeded.
Although the input of the function prototype of vec_splat_{su}{8,16,32} is
const int, the actual data usage range is limited to the data range of 5 bits
signed. We should limit the int_cst.val[0] data to the 5 bit signed data range
without any modification in the input arg0 parameter. However, the sext_hwi
function intercepts the data of TREE_INT_CST_LOW (arg0) as size bits in the
sext_hwi (TREE_INT_CST_LOW (arg0), size) statement. This will cause some of
the excess data to fall within the range of 5 bits signed, so that the correct
diagnostic information cannot be generated, we need to remove the sext_hwi to
ensure that the input data has not been modified.
This patch fix range check for the vec_splat_s[8,16,32] builtins. The argument
must be a 5-bit const int as specified for the vspltis[bhw] instructions.

Since my patch for 81359 allowed us to signal failure on return from
maybe_instantiate_noexcept, we no longer need to turn an error into
noexcept(false). We also need to handle NSDMI instantiation errors under
synthesized_method_walk. This change caused some instantiation context
notes to be lost in the testsuite, so I added push_tinst_level to
get_defaulted_eh_spec to restore that context.

In signal-triggered stack scan, if the signal is delivered at
certain bad time (e.g. in vdso, or in the middle of setcontext?),
the unwinder may not be able to unwind the whole stack, while it
still reports _URC_END_OF_STACK. So we cannot rely on _URC_END_OF_STACK
to tell if it successfully scanned the stack. Instead, we check
the last Go frame to see it actually reached the end of the stack.
For Go-created stack, this is runtime.kickoff. For C-created
stack, we need to record the outermost Go frame when it enters
the Go side.
Also we cannot unwind the stack if the signal is delivered in the
middle of runtime.gogo, halfway through a goroutine switch, where
the g and the stack don't match. Give up in this case as well.

ix86_fpmath should be set to combination of FPMATH_387 and FPMATH_SSE.
When SSE is disabled, it should be set to FPMATH_387 and 387 codegen is
also controlled by -msoft-float.
