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.

Fix stack buffer overrun when weightTotal == 0
...
If `weightTotal == 0`, then `BIT_highbit32(weightTotal)` is
undefined behavior in the case that it calls `__builtin_clz()`.
If `tableLog == HUF_TABLELOG_ABSOLUTEMAX` then we will access one
byte beyond the end of the buffer.
