Thank you for the patch.
The testcase fails in a different way with different flags; I haven't checked
if the patch helps:
$ x86_64-pc-linux-gnu-gcc -Os -mno-sse2 testcase.c
testcase.c: In function 'foo':
testcase.c:4:3: error: invalid conversion from type '__bf16' without option
'-msse2'
4 | (0 ? : f) && c;
| ^
testcase.c:4:3: internal compiler error: tree check: expected class 'type',
have 'exceptional' (error_mark) in build_int_cst, at tree.cc:1651
