IMPALA-5031: signed overflow is undefined behavior
This undefined behavior was caught with UBSAN in the end-to-end
tests. The interesting part of the backtrace is:
gutil/atomicops-internals-x86.h:283:15: runtime error: signed
integer overflow: -9223370395229620599 + -9223371946660462582
cannot be represented in type 'long'
