lz4: fix wrong compress buffer size for 64-bits
The current lz4 compress buffer is 16kb on 32-bits, 32kb on 64-bits
system. But, lz4 needs only 16kb on both. On 64-bits, this causes
wasted cpu cycles for additional memset during every compression.
In case of lz4hc, the current buffer size is (256kb + 8) on 32-bits,
(512kb + 16) on 64-bits. But, lz4hc needs only (256kb + 2 * pointer) on
both.
This patch fixes these wrong compress buffer sizes for 64-bits.
