Change the return type of function fls and clz as uint16_t;
When the input is zero, INVALID_BIT_INDEX is returned;
Update temporary variable type and return value check of caller
when it call fls or clz;
When input value is zero, clz returns 32 directly.
V1-->V2:
INVALID_BIT_INDEX instead of INVALID_NUMBER;
Add type conversion as needed;
Add "U/UL" for constant value as needed;
Codeing style fixing.
V2-->V3:
Use type conversion to remove side effect of
the variable which stores fls/clz return value;
fls return INVALID_BIT_INDEX directly when the
input value is zero.
V3-->v4:
Clean up comments for fls.
Note: For instruction "bsrl", destination register value
is undefined when source register value is zero.
