re PR target/78451 (FAIL: gcc.target/i386/sse-22a.c: error: inlining failed in call to always_inline '_mm512_setzero_ps')

	PR target/78451
	* c-pragma.c (handle_pragma_target): Don't replace
	current_target_pragma, but chainon the new args to the current one.

	* gcc.target/i386/pr78451.c: New test.
	* gcc.target/i386/pr69255-1.c: Use #pragma GCC push_options
	and #pragma GCC pop_options around the first #pragma GCC target.
	* gcc.target/i386/pr69255-2.c: Likewise.
	* gcc.target/i386/pr69255-3.c: Likewise.
