8ff321e41a Fix two issues reported by Coverity Scan and modernize class WERD_RES 
Report from Coverity Scan:

    CID 1405560 (#1 of 1): Uninitialized scalar field (UNINIT_CTOR)
    2. uninit_member: Non-static class member end is not initialized in
    this constructor nor in any functions that it calls.

    CID 1405561 [...]

Modernize and optimize class WERD_RES. This not only fixes the issues
but also reduces the size and eliminates the functions InitNonPointers
and InitPointers.

913cbe6eae Modernize and optimize BLOBNBOX and remove BLOBNBOX::ConstructionInit 
The class no longer uses bit fields. Re-ordering the member variables
avoids holes and reduces the size of BLOBNBOX from 168 to 152 bytes.

5fa09f184f RecodedCharIDHash: Fix runtime errors detected by UndefinedBehaviorSanitizer 
Fix this runtime error in recodebeam_test and unicharcompress_test:

    src/ccutil/unicharcompress.h:84:27: runtime error:
      left shift of 267 by 28 places cannot be represented in type 'int'

code has up to kMaxCodeLen (9) values, so the highest possible value for
i is 8, and the shift value can reach 7 * 8 = 56.

That requires an uint64_t data type.
size_t would fit for 64 bit hosts, but be too small for 32 bit hosts.
