fe5d27062e disable prefetch-decode for 32-bits target 
This decoder variant is detrimental to x86 architecture
likely due to register pressure.

Note that the variant is disabled for all 32-bits targets.
It's unclear if it would help for different architectures,
such as ARM, MIPS or PowerPC.

4bcc69b761 solves warnings when compiling with global XXH_STATIC_LINKING_ONLY 
XXH_STATIC_LINKING_ONLY protection macro is intended to be triggered just before the include.
The main idea is to keep this setting local :
user module shall explicitly understand and accept the static linking restriction
which becomes transparent when triggering the macro at project level.
Global definition also triggers redefinition warnings for user modules which do locally define the macro.

This new version compiles lib and cli without warning when the macro is set globally.
That's not a scenario to be recommended, since it trades a local effect for a global one,
but it was easy enough to provide from zstd side.

e474aa55b4 Fix decompression buffer overrun 
Allows an adversary to write up to 3 bytes beyond the end of the buffer.
Occurs if the match overlaps the `extDict` and `currentPrefix`, and the
match length in the `currentPrefix` is less than `MINMATCH`, and
`op-(16-MINMATCH) >= oMatchEnd > op-16`.

10bfd0c0d5 Fix ZSTD_execSequence() performance regression 
Commit ae1cb3b3d0 caused the regression.
It is an instruction alignment issue, because if it is `U64 i` instead
of `U32 i`, the regression returns.  This patch fixes the regression
in gcc, but only gets some of the clang performance back.

Benchmarks:
Run on `silesia.tar`.  I only show levels 1-5 because the performance
regression was uniform across all levels.  I did one run on levels
1-19 and it looked good.

eb7873a048 ZSTD_execSequence() accepts match in last 7 bytes 
The zstd reference compressor will not emit a match in the last 7
bytes of a block.  The decompressor will also not accept a match
in the last 7 bytes.  This patch makes the decompressor accept a
match in the last 7 bytes.

ae1cb3b3d0 Fix small bug in ZSTD_execSequence() 
`memmove(op, match, sequence.matchLength)` is not the desired behavior.
Overlap is allowed, and handled as if we did `*op++ = *match++`, which
is not how `memmove()` handles overlap.

Only triggered if both of the following conditions are met:
* The match spans extDict & currentPrefixSegment
* `oLitEnd <= oend_w < oLitEnd + length1 < oMatchEnd <= oend`.

These two conditions imply that the block is less than 15 bytes long.
This bug isn't triggered by the streaming API, because it allocates
enough space for the window size + the block size, so there cannot be
a match that is within 8 bytes of the end and overlaps with itself.
It cannot be triggered by the block decompression API because all of
the decompressed data is in the currentPrefixSegment.

4db751668f Fix buffer overrun in ZSTD_loadEntropy() 
The table log set by `FSE_readNCount()` was not checked in
`ZSTD_loadEntropy()`.  This caused `FSE_buildDTable(dctx->MLTable, ...)`
to overwrite the beginning of `dctx->hufTable`.

The benchmarks look good, there is no obvious performance regression:
