Enable use of bswap intrinsics in clang

Necessary because clang disguises itself as an older (__GNUC_MINOR__ = 2) GCC.

restored bitMask for shift values
...
since corrupted bitstreams can generate too large values.
This slightly reduces the benefits from clang on my laptop.
gcc results and code generation are not affected.

improved decompression speed
...
while reviewing #1364 ,
I found a decompression speed improvement.
On my laptop, the new code decompresses +5-6% faster on clang
and +2-3% faster on gcc.
not bad for an accidental optimization...

fixed static analyzer warnings
...
note : for some reason,
scan-build version on my laptop found problems within fastcover.c
that scan-build on travisCI does not flag.
They are, as usual, false positive :
the analyzer does not understand that a table (`offset`) is correctly filled before usage.

Revert Ability to Set HashLog and ChainLog on Context When Dict is Attached

This capability is not needed / used in the current unit of work. I'll

working context logs.

Use Working Ctx Logs when not in DMS Mode
...
We pre-hash the ptr for the dict match state sometimes. When that actually
happens, a hashlog of 0 can produce undefined behavior (right shift a long
long by 64). Only applies to unoptimized compilations, since when
optimizations are applied, those hash operations are dropped when we're not
actually in dms mode.
