[GCC][testsuite][ARM][AArch64] Add ARM v8.6 effective target checks to target-supports.exp

[Stam Markianos-Wright]

Hi all,

This small patch adds support for the ARM v8.6 extensions +bf16 and 
+i8mm to the testsuite. This will be tested through other upcoming 
patches, which is why we are not providing any explicit tests here.

Ok for trunk?

Also I don't have commit rights, so if someone could commit on my 
behalf, that would be great :)

The functionality here depends on CLI patches:
https://gcc.gnu.org/ml/gcc-patches/2019-11/msg02415.html
https://gcc.gnu.org/ml/gcc-patches/2019-11/msg02195.html

but this patch applies cleanly without them, too.

Cheers,
Stam
