Update PR middle-end/88587 tests

It is wrong to use -m32 in dg-options.  { target ia32 } should be used
instead.  Also add -fno-pic to g++.target/i386/pr88587.C since it is
invalid with PIC.

	PR middle-end/88587
	* g++.target/i386/pr88587.C (dg-do): Add { target ia32 }.
	(dg-options): Replace -m32 with -fno-pic.
	* gcc.target/i386/mvc13.c (dg-do): Add { target ia32 }.
	(dg-options): Remove -m32.
