More unused and non-deprecated warning flags
For #10752 I was looking at some warning generation code, and I realized that these flags are not doing anything right now, but they're not deprecated:
- -fwarn-tabs
- -fwarn-monomorphism-restriction
- -fwarn-unrecognised-pragmas
This one is not even shown in user manual or man page:
- Opt_WarnAlternativeLayoutRileTransitional
We should probably deprecate and remove them.
Another thing is that we should probably remove -fwarn-amp in HEAD.
