Revert "Revert "Add benchmarks that run simple programs""

This reverts commit 3bf27c86d1327a5a66bf06af07027c4f1a37d358.

Disable the 32-bit glibc target. We're not interested in benchmarking that
target, and the bench_noop_nostl executable doesn't build when ASAN is
turned on, because the libclang_rt.asan_cxx-i386.a lib contains
ubsan_type_hash_itanium.cc.o, which needs __dynamic_cast and various
STL typeinfo variables. The equivalent libclang_rt.asan_cxx-x86_64.a
lib doesn't have ubsan_type_hash_itanium.cc.o in it.

Bug: http://b/141693636
Test: m bench_noop_nostl bench_noop bench_noop_static ASAN_OPTIONS=detect_leaks=0 SANITIZE_HOST=address
