llvm: Using typecast for consisting 32b/16b. 



We usually to constitute an (uin32_t) with 4 (uint8_t)s.
or an (uin16_t) with 2 (uint8_t)s.
If you not to force type change, there may be overflow.
Then you would get the wrong value.

Meanwhile elimating the warning catched my the analyzer.

Fixes issue #2549.
