runtime: disable split stacks for runtime_printf function under Clang

LLVM's code generator does not currently support split stacks for vararg
functions, so we disable split stacks for the only function that uses this
feature under Clang. This appears to be OK as long as:
- this function only calls non-inlined, internal-linkage (hence no dynamic
  loader) functions compiled with split stacks (i.e. go_vprintf), which can
  allocate more stack space as required;
- this function itself does not occupy more than BACKOFF bytes of stack space
  (see libgcc/config/i386/morestack.S).
These conditions are currently known to be satisfied by Clang on x86-32 and
x86-64. Note that signal handlers receive slightly less stack space than they
would normally do if they happen to be called while this function is being
run. If this turns out to be a problem we could consider increasing BACKOFF.

Note dc=0x1, which is obviously a bogus pointer.  This is the end of
d_dump recursing for a component type that that doesn't actually have
subtrees:

 787       d_dump (d_left (dc), indent + 2);
 788       d_dump (d_right (dc), indent + 2);

This fixes the two cases the testsuite currently trips on.
