It looks to me that the fix for PR90497 is not entirely correct, because it
allows to bypass builtins that have additional SSE* restrictions.
The following test also fails with -mmmx -msse -mno-sse2 (or -m32):
ttt.c: In function ‘foo’:
ttt.c:8:1: error: unrecognizable insn:
8 | }
| ^
(insn 9 8 10 2 (set (reg:V2DF 85)
(float:V2DF (reg:V2SI 86))) "ttt.c":7:10 -1
(nil))
during RTL pass: vregs
