Fix PR target/103274

[Eric Botcazou]

This fixes a thinko in my fix for the -freorder-blocks-and-partition glitch 
with SEH on 64-bit Windows:
  https://gcc.gnu.org/pipermail/gcc-patches/2021-February/565208.html

Even if no exceptions are active, e.g. in C, we always need to consider calls.

Tested on x86-64/Windows, applied on mainline, 11 and 10 branches as obvious.

	* config/i386/i386.c (ix86_output_call_insn): Beef up comment about
	nops emitted with SEH.
	* config/i386/winnt.c (i386_pe_seh_unwind_emit): When switching to
