[PATCH 2/5] Convert Walloca pass to RANGE_QUERY(cfun).

[Aldy Hernandez]

On x86-32 warn_ptrdiff_anti_range_add() and warn_int_anti_range()
degrade to the same function so ICF is folding the latter into a call
into the former.  This is causing no warnings to be emitted for
warn_int_anti_range.

Fixed by passing -fno-ipa-icf to the test.

Long term, we really should be finding a way to run these warning
passes earlier :-/.

Pushed.
