delete.
MallocChecker no longer thinks that operator delete() that accepts the size of
the object to delete (available since C++14 or under -fsized-deallocation)
is some weird user-defined operator. Instead, it handles it like normal delete.
Additionally, it exposes a regression in NewDelete-intersections.mm's
testStandardPlacementNewAfterDelete() test, where the diagnostic is delayed
from before the call of placement new into the code of placement new
in the header. This happens because the check for pass-into-function-after-free
for placement arguments is located in checkNewAllocator(), which happens after
the allocator is inlined, which is too late. Move this use-after-free check
into checkPreCall instead, where it works automagically because the guard
that prevents it from working is useless and can be removed as well.
This commit causes regressions under -analyzer-config
c++-allocator-inlining=false but this option is essentially unsupported
because the respective feature has been enabled by default quite a while ago.
