Add benchmarks that run simple programs
Specifically, test the wall-clock time for running:
* a C program that does nothing (i.e. no STL)
* a C++ program that does nothing
* a statically-linked C++ program
* toybox true (in /system/bin and /vendor/bin)
* mksh -c true (in /system/bin and /vendor/bin)
Test: bionic-spawn-benchmarks
