Log Message:
-----------
[HLSL] Add NativeInt16Type langopt to control whether short type is supported. Enabled by default for all but HLSL. (#165584)
Add a new langopt NativeInt16Type to control support for 16 bit
integers.
Enable by default for all languages but HLSL.
HLSL defines uint16_t and int16_t as a typedef of short. If
-enable-16bit-types is not used, the typedefs don't exist so int16_t and
uint16_t can't be used. However, short was still allowed. This change
will produce an error 'unknown type name short' if -enable-16bit-types
isn't used.
Update failing tests.
Add new test.
Closes #81779
