I can sympathize with wanting to test the end-to-end behavior, but maybe that could be put in a separate test, and use only one or two allocator variants? The point is mainly to check that the pass pipeline is set up right both for -O0 and higher, right?

The current version of the patch, which combines -O0, -O, and -disable-llvm-passes with all the different allocators, and uses generated checks, makes it very hard to see what behavior it's actually testing for.
