[GCC][Patch]Bug fix: cannot convert 'const short int*' to 'const __bf16*'

[Delia Burduv]

This patch fixes a bug introduced by my earlier patch ( 
https://gcc.gnu.org/pipermail/gcc-patches/2020-March/541680.html ).
It introduces a new scalar builtin type that was missing in the original 
patch.

Bootstrapped cleanly on arm-none-linux-gnueabihf.
Tested for regression on arm-none-linux-gnueabihf. No regression from 
before the original patch.
Tests that failed or became unsupported because of the original tests 
now work as they did before it.
