When running the gcc testsuite with current aarch64-linux-user,
the testsuite detects the presence of the fp16 extension and
enables lots of extra tests for builtins.
Quite a few of these new tests fail because we missed implementing
some instructions. We really should go back and verify that nothing
else is missing from this (rather large) extension.
In addition, it tests some edge conditions on data that show flaws
in the way we were performing integer<->fp conversion; particularly
with respect to scaled conversion.
Changes since v1:
* Rebased vs master instead of tgt-arm-sve-9.
* Alex did some additional digging through the ARM xhtml
and came up with some additional missing instructions.
* Everything cc'd to qemu-stable.
