Revert 246129 "PPAPI: Make ASSERT macros print values of operands"

PPAPINaClGLibcTest.WebSocket and PPAPINaClGLibcTest.FileRef are timing out on
Win7 Tests (dbg)(4) and PPAPINaClGLibcTest.URLLoader is timing out on
Win7 Tests (dbg)(6).

> PPAPI: Make ASSERT macros print values of operands
> 
> With this patch, if one of our ASSERT macros fails, the error
> string will contain the expected and actual values.
> 
> I made a browser test for it. I would prefer a
> unit test, but I didn't want to have to mix test_case.h with
> our unit tests.
