[PATCH 2/2] gdb: Enable finish command and inferior calls for _Float16 on amd64 and i386.

They are the same usually, but on ARM the story is apparently a bit more complex:
https://gcc.gnu.org/onlinedocs/gcc/Half-Precision.html

But to cite the link:
" The __fp16 type may only be used as an argument to intrinsics defined in
<arm_fp16.h>, or as a storage format."

And:
"It is recommended that portable code use the _Float16 type defined by
ISO/IEC TS 18661-3:2015."

Therefore I don't think it is that unfortunate and not really negotiable by now.
Both GCC and clang know about both already.

Thanks for spotting this. I fixed it locally.

Thanks. I reworded it to say:
"Test program for _Float16 parameters and return values."
