I have only minor comments

http://gerrit.cloudera.org:8080/#/c/8833/4/be/src/benchmarks/overflow-benchmark.cc
File be/src/benchmarks/overflow-benchmark.cc:

http://gerrit.cloudera.org:8080/#/c/8833/4/be/src/benchmarks/overflow-benchmark.cc@137
PS4, Line 137:   return false;
This now always returns false.


http://gerrit.cloudera.org:8080/#/c/8833/4/be/src/runtime/decimal-value.inline.h
File be/src/runtime/decimal-value.inline.h:

http://gerrit.cloudera.org:8080/#/c/8833/4/be/src/runtime/decimal-value.inline.h@186
PS4, Line 186:   return num_lz - floor_log2[scale_diff] - 1;
num_lz - floor_log2[scale_diff] - (scale_diff > 0)

is slightly nicer, but may not matter since I don't think this is ever called 
for scale_diff == 0
