I enabled the test again.

The CHECK-NOT was picking up the file path that llvm-objdump prints, I fixed that. llvm-objdump no longer crashes, so I have no idea why that was happening. We have refreshed all the bot containers since then, that could have "fixed" it.

Unfortunately I got more failure notifications like:
```
# .---command stdout------------
# | FMOVWSr: Not all operands were initialized by the snippet generator for UMOVvi32 opcode.
# `-----------------------------
```
And I don't think it's worth the spam to leave this enabled. Please fix the errors before enabling it again.
