073fe18edf [ossfuzz] Fix parallel builds 
With `make -j` multiple builds of `standaloneengine.o` happened in
parallel. Fix this by detecting `standaloneengine.o` and moving it to a
depedency.

0e3933edd4 Replace "static" to "LZ4_FORCE_INLINE" for small functions 
The "static" specifier does not guarantee that the function will be inlined.

749bd91a06 Replace define LZ4_FORCE_O2_INLINE_GCC_PPC64LE to LZ4_FORCE_INLINE 
There is no reason to separate these two definitions!

c4792cdfa9 Fix: The "inline" specifier do not use for LZ4_wildCopy8 and LZ4_wildCopy32 
This problem was reproduced on MSVC 2015 (32-bit). Both functions were called using the operator "call".

e7fe105ac6 fix efficiency of LZ4_compress_HC_destSize() 
LZ4_compress_HC_destSize() had a tendency
to discard its last match when this match overflowed specified dstBuffer limit.
The impact is generally moderate,
but occasionally huge,
typically when this last match is very large
(such as compressing a bunch of zeroes).

Issue #784 fixed for both Chain and Opt implementations.

Added a unit test suggested by @remittor checking this topic.

Add CMake option LZ4_BUILD_CLI. 
Defaults to ON so nothing changes, but it can be set to OFF so that the
CLI is not built at all, only the library.

b223f11b21 ubsan: make pointer overflow recoverable 
the way `base` is used must allow 2-complement address overflow.
`base` is effectively a virtual pointer, never dereferenced directly.
What matters is `base + index`.
This is the address that will be dereference and must be valid (it is properly validated).
