Support type _Float16/__bf16 independent of SSE2.
Enable _Float16 and __bf16 all the time but issue errors when the
types are used in conversion, unary operation, binary operation,
parameter passing or value return when TARGET_SSE2 is not available.
Also undef macros which are used by libgcc/libstdc++ to check the
backend support of the _Float16/__bf16 types when TARGET_SSE2 is not
available.
gcc/ChangeLog:
PR target/109504
* config/i386/i386-builtins.cc
(ix86_register_float16_builtin_type): Remove TARGET_SSE2.
(ix86_register_bf16_builtin_type): Ditto.
* config/i386/i386-c.cc (ix86_target_macros): When TARGET_SSE2
isn't available, undef the macros which are used to check the
backend support of the _Float16/__bf16 types when building
libstdc++ and libgcc.
