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.

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.

Fix execSequence wildcopy undefined behavior

execSequence relied on pointer overflow to handle cases where
`sequence.matchLength < 8`. Instead of passing an `size_t` to
wildcopy, pass a `ptrdiff_t`.

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`.
