Add implementation of count_leading_zeros<LL>

Clang seems to think that timestamp_t^timestamp_t is a long-long (rather than be either unsigned or a plain long like gcc does). This patch adds an implementation for <long long> (modeled off of <long>) that properly compiles. Signed-off-by: Erich Keane <[email protected]> Message-Id: <[email protected]>
