Force-Inline ZSTD_insertAndFindFirstIndex_internal()
...
Without this, gcc was declining to inline the function in `ZSTD_noDict` mode,
resulting in a ~10% slowdown.

Permit Matching Against Lowest Valid Position
...
This comparison was previously faulty: the lowest valid position is itself
valid, and we should therefore be allowed to match against it.

Remove Chain Limit on Hash Cache Entries; Slightly Improve Compression
...
Entries in the hashTable chain cache aren't subject to the same aliasing that
the circular chain table is subject to. As such, we don't need to stop when we
cross the chain limit. We can delve deeper. :)
