[WebAssembly] Improve lto/comdat.ll test. NFC.

We were not previously testing the comdat exclusion in bitcode objects
because we were linking two copies of the .bc file and the
`linkonce_odr` linkage type was removing the duplicate `_start` at
the LTO stage.

Now we link an bitcode and non-bitcode version both of which contains a
copy of _start.  We link them in both orders, which means this test will
fail if comdat exclusion is not working correctly in bitcode parsing.

Benchmarking

In order to make sure various developers can evaluate patches over the same tests, we create a collection of self contained programs.
