[InstCombine] Mark select in fdiv transforms with unknown profile (#177759)
As part of the profcheck effort we are trying to explicitly annotate
select instructions where we cannot reasonably synthesize profile
information as having an unknown profile. This does that for the case
introduced in 0993d69bc35cfdd4f3a904a603701e66906e8987.
Reapply "[VPlan] Move VDef subclass ID to VPRecipeBase (NFC). (#174282)"
Move SubclassID to VPRecipeBase, and store VPRecipeBase directly in
VPRecipeValue, instead of VPDef. This allows for some additional
simplifications and VPDef now just holds various helpers to deal with
removing and adding VPValues.
This reverts commit 16395da0ff577750571b99fe28281ce6fb6a3ae8.

Committed with out-of-date message, revert to reland with updated

firewall: lowercase for protocol values required for DNAT
Use the ChangeCase BaseField extension because it's already being tested
and add more tests and safeguards so that the cache knows which case is
going on (also if 'any' needs to be used).
The 'any' value is a bit tricky here. Force it to lowercase in all cases
since it wasn't uppercased before either.
Also fix the display of anti-lockout protocol for consistency.
InstCombine: Clean up SimplifyDemandedFPClass use context application (#176886)
Clean up some now redundant propagation of known-result to known-source
cases. Also move the application of the demanded mask to individual
cases, since the intermediate results are often used.
[ProfCheck] Add new InstCombine test to xfail list
The fix should be quick, but just in case it takes a while to land, add
it to the xfail list so we can catch any future regressions more easily.
[NFCI][AMDGPU] Move more attributes from `AMDGPUSubtarget` to `GCNSubtarget` (#177670)
They are simply not used by `AMDGPUSubtarget &` but directly via
`GCNSubtarget &`.
