Build with the same options (-O2, Emscripten -s MODULARIZE, etc.) as tsf-wasm before. Use the WasmEMCCBenchmark class introduced earlier. Since we want to run multiple iterations (for first, average, worst scoring), change to small workload size. Each individual iteration still runs >20ms, which we agreed on in the last sync.

Drive-by fixes:
The WasmEMCCBenchmark setup code needs to make sure we don't automatically run main() after setupModule(), hence add noInitialRun. The TSF-wasm build script uses set -o pipefail, which is a bash option, hence change shebang line. Add Wall time output also for WasmLegacyBenchmark.

I compared profiles/flamegraphs before and after the recompilation of gcc-loops.wasm. We still spend the vast majority of the CPU samples in top-tier compiled code, which makes sense.

it can accommodate n elements such that n = vector-size/element-size
(e.g, 4 ints, 8 shorts, or 16 chars for a vector of size 16 bytes).
A combination of data-types of different sizes in the same loop
Currently only a single vector-size per target is supported;
