Simplify rotg
...
* The check da != ZERO is no longer necessary since there
is a special case ada == ZERO, where ada = |da|.
* Add the missing check c != ZERO before the division.
Note that with these two changes the long double code
follows the float/double version of the code.

Fix division by zero in zrotg
...
The cases
[ c s ] * [ 0 ] = [ |db_i| ]
[-s c ] [ i*db_i ] [ 0 ]
and
[ c s ] * [ 0 ] = [ |db_r| ]
[-s c ] [ db_r ] [ 0 ]
computed s incorrectly. To flip the entries of vector,
s should be conjg(db)/|db| and not conjg(db) / da,
where da == 0.0.

Add bfloat16 based dot and conversion with single/double
...
1. Added bfloat16 based dot as new API: shdot
2. Implemented generic kernel and cooperlake-specific (AVX512-BF16) kernel for shdot
3. Added 4 conversion APIs for bfloat16 data type <=> single/double: shstobf16 shdtobf16 sbf16tos dbf16tod
shstobf16 -- convert single float array to bfloat16 array
shdtobf16 -- convert double float array to bfloat16 array
sbf16tos -- convert bfloat16 array to single float array
dbf16tod -- convert bfloat16 array to double float array
4. Implemented generic kernels for all 4 conversion APIs, and cooperlake-specific kernel for shstobf16 and shdtobf16
5. Update level1 thread facilitate functions and macros to support multi-threading for these new APIs
6. Fix Cooperlake platform detection/specify issue when under dynamic-arch building
7. Change the typedef of bfloat16 from unsigned short to more strict uint16_t
