Ryan Prichard f82e39f1d9 Add a liblog dependency 
Modules with a libbase dependency also need a liblog dependency now.

Fixes the linker-reloc-bench build target.

Ryan Prichard 41f19708c8 Add a linker relocation benchmark 
The benchmark creates a set of DSOs that mimic the work involved in
loading the current version of libandroid_servers.so. The synthetic
benchmark has roughly the same number of libraries with roughly the same
relocations.

Currently, on a local aosp_walleye build that includes recent performance
improvements (including the Neon-based CL
I3983bca1dddc9241bb70290ad3651d895f046660), using the "performance"
governor, the benchmark reports these scores:
