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".

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.

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).

LZ4_decompress_safe_partial()
now also supports a scenario where
nb_bytes_to_generate is <= block_decompressed_size
And
nb_bytes_to_read is >= block_compressed_size.
Previously, the only supported scenario was
nb_bytes_to_read == block_compress_size.
Pay attention that,
if nb_bytes_to_read is > block_compressed_size,
then, necessarily, it requires that
nb_bytes_to_generate is <= block_decompress_size.
If both are larger, it will generate corrupted data.
