Issue a warning for conversion between short and __bf16 under TARGET_AVX512BF16.
__bfloat16 is redefined from typedef short to real __bf16 since GCC
V13. The patch issues an warning for potential silent implicit
conversion between __bf16 and short where users may only expect a
data movement.
To avoid too many false positive, warning is only under
TARGET_AVX512BF16.
gcc/ChangeLog:
* config/i386/i386.cc (ix86_invalid_conversion): New function.
(TARGET_INVALID_CONVERSION): Define as
ix86_invalid_conversion.
gcc/testsuite/ChangeLog:
* gcc.target/i386/bf16_short_warn.c: New test.
